Can you send me a list of plugins you use besides the ActivityPub plugin?

The model class was removed in 2.0.0 but it is no longer in use since month, so it might be a third party plugin using it?!?

[nesges]

Sure! Istalled but inactive is marked with brackets

[nesges]

The model class was removed in 2.0.0 but it is no longer in use since month, so it might be a third party plugin using it?!?

root@gond:/var/www/html/d3/dnddeutsch.de/wordpress/wp-content/plugins# grep -irl 'ActivityPub' .
./webmention/includes/class-receiver.php
./autopost-to-mastodon/instanceList.php
./webfinger/readme.txt
root@gond:/var/www/html/d3/dnddeutsch.de/wordpress/wp-content/plugins# grep -ir 'ActivityPub' ./webmention/includes/class-receiver.php
                        // This would catch incoming activitypub matches, which uses source_url

autopost-to-mastodon is inactive and webmention, well you know it better than me, I guess ;-) What else would I grep the plugins for?

[pfefferle]

can you try to clear all caches and then re-check? it seems that no plugin is using the class 😳

[nesges]

I tried clearing WP Super Cache and restarting Apache2 but still no luck. One thing has changed: The error appears on activation of ActivityPub only, which then fails and leaves the plugin inactive. So it doesn't break the site anymore

[nesges]

some more greping over the whole installation:

root@gond:/var/www/html/d3/dnddeutsch.de/wordpress# grep -irl 'ActivityPub' . | grep -v '/plugins/activitypub/'
./wp-content/plugins/webmention/includes/class-receiver.php
./wp-content/plugins/webfinger/readme.txt
./wp-content/languages/plugins/activitypub-de_DE.po
./wp-content/languages/plugins/activitypub-de_DE.mo
root@gond:/var/www/html/d3/dnddeutsch.de/wordpress#

[pfefferle]

Can you run the grep one folder above (wp-content) to also check mu-plugins and themes?

[pfefferle]

And can you maybe also search directly for Activitypub\Model\Post in the ActivityPub plugin folder?

[nesges]

root@gond:/var/www/html/d3/dnddeutsch.de/wordpress# grep -irl 'Activitypub.*Model.*Post' .
root@gond:/var/www/html/d3/dnddeutsch.de/wordpress#

This is odd. It should have found any mention of "Activitypub Model Post" including "Activitypub\Model\Post", ""Activitypub:Model:Post" etc. pp. anywhere in my installation, including wp-content/mu-plugins and themes but it just isn't there 🤔

[nesges]

Can you run the grep one folder above (wp-content) to also check mu-plugins and themes?

they were already included since grep startet at the installation base (/var/www/html/d3/dnddeutsch.de/wordpress)

[nesges]

Maybe anything in the database? I could search a dump 🤷

[ragnar76]

today, i stumbled across the same error. I have these plugins installed:

Is there anything i can do to help?

[pfefferle]

Can you update the enable-mastodon-apps to the latest version?

[ragnar76]

Last night, all plugins where uptodate, this morning there was indeed an update for enable-mastodon-apps. will do the update, reinstall Activitypub and test again

[ragnar76]

Nope, no luck :(

[pfefferle]

Do you use some kind of PHP cache like opcache for example? Can you try clearing that too?

[ragnar76]

I don't use a caching system

[nesges]

I just tried deactivating all plugins, restarting apache2 and activating only ActivityPub, but the error stays. After that I even emptied the plugin-folder wp-content/plugins/ completely and tried activating ActivityPub with the same result. Please let me know if I can test something else!

[nesges]

PS: can send phpinfo() via Mastodon-DM if it's of interest

[pfefferle]

@ragnar76 can you try to deactivate the friends plugin and re-check?

[ragnar76]

Yes, i did. No luck. It still breaks down

[pfefferle]

can one of you try to create the following file includes/model/class-post.php with this content:

<?php
namespace Activitypub\Model;

class Post {

}

[nesges]

That did the trick, the plugin is active now on my site!

[pfefferle]

can you browse one of your posts and add ?activitypub at the end of the URL... does it show proper JSON?

[nesges]

looking good! https://www.dnddeutsch.de/adventsbasteln-mit-dd/?activitypub

[pfefferle]

this is so weird 🤔

[mauriziomarini]

can one of you try to create the following file includes/model/class-post.php with this content:

<?php
namespace Activitypub\Model;

class Post {

}

it's ok here, too https://www.informapirata.it/ https://www.informapirata.it/?activitypub

[informapirata]

can one of you try to create the following file includes/model/class-post.php with this content:

Hallo Matteo! Ich hatte gestern Abend das gleiche Problem mit der Informapirata.it-Site, direkt nach der Aktualisierung des Plugins.

Mein Blog war zuvor perfekt innerhalb der Föderation integriert, wie Sie hier sehen können: https://lemmy.world/post/10356319 aber dann wurde es unerreichbar

Bisher bestand die einzige Möglichkeit, das Problem zu lösen, darin, den Ordner „activity_pub“ mit dem Plugin zu löschen, das den Fehler verursachte, aber dank der von Ihnen vorgeschlagenen Änderung funktioniert die Site jetzt endlich

[pfefferle]

Can you tell me which PHP version you use?

[mauriziomarini]

8.0.2 thx

[pfefferle]

Can one of you maybe remove the class-post.php once again (or rename it) and uncomment this line: https://github.com/Automattic/wordpress-activitypub/blob/48a33b82e929725cdcd358c4b87fc188ec25764a/activitypub.php#L125

Maybe we can see the stacktrace then!

[pfefferle]

sorry for the inconvenience but i would like to understand what exactly the problem is!

[mauriziomarini]

sorry for the inconvenience but i would like to understand what exactly the problem is!

I renamed

mv includes/model/class-post.php includes/model/class-post.php_

now it is: if ( file_exists( $file ) && is_readable( $file ) ) { require_once $file; } else { // translators: %s is the class name wp_die( sprintf( esc_html__( 'Required class not found or not readable: %s', 'activitypub' ), esc_html( $full_class ) ) ); } it was \wp_die I changed to wp_die

but no stack trace, still the usual error message

[nesges]

sorry for the inconvenience but i would like to understand what exactly the problem is!

no worries, I'm fascinated of the process :-) I also added

// \wp_die( ...
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

and this is what went to error.log:

seems unrelated though

[informapirata]

Maybe we can see the stacktrace then!

Sobald Sie die von Ihnen vorgeschlagene Änderung vorgenommen haben, sind Sie wieder da, wo Sie angefangen haben, mit der gleichen Fehlermeldung

Classe richiesta non trovata o non leggibile: Activitypub\Model\Post

Trans: Angeforderte Klasse nicht gefunden oder nicht lesbar: Activitypub\Model\Post

[nesges]

Maybe this is a clue: I generated a debug_backtrace() and found a serialized activitypub_send_delete_activity in wp_options that references Activitypub\Model\Post. Here's the full output of debug_backtrace: https://www.dnddeutsch.de/wp-content/uploads/debug-backtrace.txt

(Edit: reuploaded the tracefile)

[pfefferle]

Oh, this helps a lot... I will see if I can cleanup the cronjobs during the update! Thanks a lot you all!

[nesges]

Happy to help! Thanks for your work!

[ragnar76]

can one of you try to create the following file includes/model/class-post.php with this content:

<?php
namespace Activitypub\Model;

class Post {

}

Late to the party (my couch was very appealing yersterday ;) ) but when i add this file, it works here too

[ThomasKujawa]

class Post {

}

Update to 2.0.0 resulted in the above error. With this update our site is running again.

If you need further information, please contact us.

Can you run the grep one folder above (wp-content) to also check mu-plugins and themes?

I got some results in the autonomie theme, which I did update from git a few minutes ago.

Something like this:

utzer@web /path/to/wp-content % grep -irl 'ActivityPub' ../
../wp-content/languages/plugins/activitypub-de_DE.po
../wp-content/languages/plugins/activitypub-de_DE.mo
../wp-content/themes/autonomie/.git/index
../wp-content/themes/autonomie/assets/sass/openwebicons.scss
../wp-content/themes/autonomie/assets/sass/integrations.scss
../wp-content/themes/autonomie/integrations/activitypub.php
../wp-content/themes/autonomie/languages/de_DE.po
../wp-content/themes/autonomie/languages/nl_NL.po
../wp-content/themes/autonomie/languages/autonomie.pot
../wp-content/themes/autonomie/readme.txt
../wp-content/themes/autonomie/readme.md
../wp-content/themes/autonomie/functions.php
../wp-content/themes/autonomie/style.css
../wp-content/plugins/nodeinfo/readme.txt

Is this of any help?

Sorry for making a fuss about it here, I will stop that. (Couldn't find the right place to report issues.)

For anyone else coming here, to temporary deactivate the ActivityPub plugin go to the folder "wp-content/plugins" and move/remove "activitypub", then open /wp-admin/plugins.php which will deactivate the plugin because it can't find the folder/files for the plugin. Updated plugin is available now, this solve my problem.

[pfefferle]

I just re-added the file in 2.0.1 that it no longer breaks you installs! That does not fix the issue, but your installs seem no longer broken!

Sorry for the trouble!

No worries, we're just happy that you put in the work and effort.

[pfefferle]

@utzer Can you maybe try to update and see if it is fixed then?

I installed the plugin again, activated it for the network and it works. Also I did a probe for @utzer@plopp.utzer.de, which return valid information.

Beim @ragnar76 gehts wohl auch wieder.
