1.8.4 - Reference Error - wp is not defined

[colbyalbo]

after updating to 1.8.4, the console logs this Reference error.

Reference Error - wp is not defined, and points to file " Caldera-forms/clients/render/build/index.min.js

No visible effect on the front end that i can tell

screenshots attached

[colbyalbo]

upon further testing, it seems this is preventing the form from submitting. I'll post the JS console errors later

[salihkulangara]

While trying to fix this, I see when we load wp-embed scripts, the error goes and forms working back again. But it seems not ok, because most of the time to reduce the JS load size we are de-registering the wp-embed scripts, right?

Hello @colbyalbo , could you share the information asked in the template ?

• share the debug information from your WordPress admin at Caldera Forms -> Support under the debug information tab
• report if the issue persists with all other plugins disabled and theme twentynineteen activated.
• share PHP and JS logs

Another user reported this issue and had it fixed by deactivating and reactivating plugins, #3144

@salihkulangara thank you for investigating this, we fixed a similar issue in previous version, what happened was that wp was not loaded if WordPress version was older than 5.0.0, we are now loading to prevent this issue. Loading wp-embed script probably enqueued wp, which solved the issue on your installation.

Also be sure to have all caches fully flushed to test that issue.

In this helpscout ticket - https://secure.helpscout.net/conversation/830660038/20516/ We see this error. An optimization plugin of some sort is being used here. I will ask which one. 97% chance this is an issue with an "optimization"

[truloveliaison]

I think this is related to my problem, as well: Seeking to try Caldera Forms-downloaded and activated....However, none of the buttons are working in admin. Thus, have no way to create a new form.... The only link that seems to work are those that target Caldera site page.....

[toukira54]

i tried disabling the the WP-Rocket and other plugin but still facing the same issue. And I don't see any solution on this ticket. #3178 this is closed. What should be the ideal solution ?

[Shelob9]

@toukira54 It would be helpful us find causes of this issue, providing a URL to the affected form and the debug information from the Caldera Forms support menu would be awesome for us.

If you need help right away, please contact technical support https://calderaforms.com/support

[colbyalbo]

Sorry for the delay. Here is the info from a local install of a replicated site. and screenshot of JS console errors

• The issue DID NOT persist once all other plugins were deactivated and twentynineteen theme activated

• I reactivated plugins one by one, and once WP Rocket was reactivated , the error came back

• I then reactivated GeneratePress theme and all other plugins , and deactivated WP Rocket, and the issues went away

Here is the my catch, as I said earlier I believe there is some relation with wp-embed scripts, because 1# In none of my sites I am using WP Rocket plugin, in some sites without any cache plugins also I am getting this error. So after digging in to this I have enqueued wp-embed through my functions.php and the issue fixed.

2# In some of our other sites we are using W3TC, in some of these sites I could see the same error, so while playing around, I found these sites were combining and loading scripts manually using W3TC, So I have changed the order of loading the wp-embed script that was loading in footer, I changed it to load in header, so that issue also fixed.

in my previous thread I got reply like

@salihkulangara thank you for investigating this, we fixed a similar issue in previous version, what happened was that wp was not loaded if WordPress version was older than 5.0.0, we are now loading to prevent this issue. Loading wp-embed script probably enqueued wp, which solved the issue on your installation.

but it seems still the issue persisits. So WP Rocket users try these for a quick fix: please check if you are combining and minifying the scripts, then load the wp-embed scrips above caldera scripts, that may fix the issue. If no wp-embed scripts, then manually load them using wp_enqueue_scripts in header.

Thank you @colbyalbo and @toukira54 for the details. To make sure there is no need to deactivate WP Rocket, could you confirm that the issue is fixed when you turn off the "disable embeds" option in WP Rocket ? ( make sure the cache is flushed to test again and page reloaded using ctrl + F5 )

Hello @salihkulangara and thank you for this useful information, in scenario 1 when no optimization plugin is used, did you identify why wp-embed was dequeued ?

[toukira54]

@New0 Hi, the error is not available when we turn of turn off "disable embeds" but then it start giving error for some other plugin.

[colbyalbo]

@New0 Confirmed. Once the "disabled embeds" options is unchecked, the issue is fixed and the form submits properly

thanks

[shaneonabike]

I can confirm that ensuring the wp-embed is added works. This should certaintly be documented somewhere as I had removed it to optimize a website and looooooong forgot that it was gone. It was only this bug report that helped me determine the issue. Furthermore, this only just started not working so I don't fully understand unless you folks have changed the way that you are injecting forms now?

[jonbhanson]

I also had to enqueued wp-embed to fix the 'wp is not defined' error.

[maxleistner]

I got the same error, but i am not using any compression or caching plugins like WP Rocket. PHP 7.2 WP 5.2.1 Caldera Forms 1.8.5

Any ideas?

@Shelob9

[maxleistner]

I found out, that if i include the file /wp-includes/wp-embed.min.js the forms do work again. But why should i add the script myself? Where can i decide if the js should be included or not?

[Shelob9]

Most likely this is happening beacuse you disabled emojis. In 1.8.6 there is a more clear warning.

How can i disable/enable emojis?

[shaneonabike]

Within the settings of WP Rocket you can improve performance by disabling emojicons. There's a switch there that you should check out.

[jevgenijmokrousov]

In my case it was wp_deregister_script('wp-embed'); in parent theme, which couldn't be changed so I've added in child theme wp_enqueue_script('wp-embed-calderaform', includes_url('js/wp-embed.js'), array());

[saurabh172]

I am also facing this issue.

If I try with metabox in my custom post then its Ok. but In case of admin menu page of my custom plugin then Wordpress media library is not being opened. Even I have not used WP Rocket plugin as well as optimize plugin. I have Yoast SEO but I have already disabled it. Please reply.

[colbyalbo]

The plugin is abandoned i think. It always had problems anyway. Consider ninja forms
