We also use CKEditor4 through FOSCKEditorBundle for our back office tools. It stopped working yesterday afternoon.

[TPSONLINE-INFO]

Sounds it’s due to a package update as two weeks ago ckeditor.js wans’t using LTS CKE4 but classic licence

[nicocau]

Hello,

I have found a workaround solution. By installing the previous version of CKEditor, you can make it work again.

php bin/console ckeditor:install --tag=4.22.1

However, this is not very clean and prevents you from having the latest versions.

Have a great day.

[pfpro]

same issue here (with php 8.2 / symfony 6.3.3)

[TPSONLINE-INFO]

Sounds that it’s the strategy of ckeditor. The workaround offered is working. Thinking about moving off ckeditor…

[antoinemineau]

thanks @nicocau for the command but you have to update your assets after running it.

bin/console ckeditor:install --tag=4.22.1
bin/console assets:install

Also you should remove the ckeditor:install from the auto-scripts in composer.json or lock it to 4.22.1 If you don't do that each time you run composer install it will download the last version and it won't work.

    "scripts": {
        "auto-scripts": {
            "ckeditor:install --tag=4.22.1": "symfony-cmd"
        },

[TPSONLINE-INFO]

Yes i put "friendsofsymfony/ckeditor-bundle": "*",

and then "scripts": { "auto-scripts": { "ckeditor:install --tag=4.22.1": "symfony-cmd", "assets:install %PUBLIC_DIR%": "symfony-cmd", "cache:clear": "symfony-cmd" }, "post-install-cmd": [ @." ], "post-update-cmd": [ @." ] },

It works perfectly

It's still not working..

[jayesbe]

I got around the error by committing a local copy of a working version of ckeditor.js to overwrite the one that gets installed.

ie

bin/console ckeditor:install --tag=4.22.1 bin/console assets:install cp ckeditor.js web/bundles/fosckeditor/ckeditor.js

[alexandre-mace]

@jayesbe I tried your solution and its not working either, which local copy version did you download ?

[jayesbe]

@jayesbe I tried your solution and its not working either, which local copy version did you download ?

@alexandre-mace I had a previous version stored which did not already have that license bit added. So I hard copied that into my code base and in the composer.json I added a line to overwrite the installed file with the copy.

GitHub won't just let me upload the file here directly.. so here's a download link https://file.io/vUNN7TXDGAn8 hope it works.

[alexandre-mace]

Sadly its still not working for me but thank you for the file !

The link is already broken

There you go @Gumbraise, https://we.tl/t-79OfSRcLPZ, the file is working i had client cache 😂

[Amunak]

In case you use ckeditor from the "built" NPM package you can also just patch out the check with patch-package if necessary.

Make sure you did actually buy the LTS license - surely you wouldn't want to break it. 🙄

I'd also like to point out that relicensing and adding license checks in a minor version that you then release instead of the original working package is a major dick move.

[peterbruins]

I was able to fix this:

bin/console ckeditor:install --tag=4.22.1
bin/console assets:install

Then, perform a hard refresh in your browser. The previous ckeditor.js may be cached. This was the reason this did not seem to work at first for me.

Same - i was able to get it running via: bin/console ckeditor:install --tag=4.22.1 drop the directory and reinstall CKEditor bin/console assets:install and it works like a charm.

[GaetanMedas]

If you are using NPM, use : npm install --save ckeditor4@4.22.1 then : npm run dev

that works just fine, i also had additional warning/error in the chrome console about the exportpdf plugin. i edited the config.js file and add config.removePlugins = 'exportpdf';

[xDeSwa]

bin/console ckeditor:install --tag=4.22.1 automatically installed 4,23 so same error. yarn add ckeditor4@4.22.1 automatically installed 4,23 so same error.

npm install --save ckeditor4@4.22.1 this works # installed 4.22.1

EDIT : config option versionCheck: false Fixed 🥇

Someone has the message ? How to disable it ? Thx

[Jean-Gian]

Does anyone have purchased the license for the extended version? (On the site it doesn't even say how much it is) If you did, where did you put the license key?

[pfpro]

yeah, @ckeditor crew: make us a nice offer !

[DMeloni]

We have to be pragmatic: the company behind CKEditor is clearly out to make money.

They are capable of paying developers to display invasive pop-ups several months after the release of CKEditor 5 in order to put pressure on companies.

We, developers, have two choices: give in to blackmail and pay for a solution (which is pretty crap because the HTML generated by your textarea is clearly bad), or switch to a simpler, more open source tool (thanks to the developers of VLC for showing that there aren't only bastards on earth) which perfectly meets the need, namely: just people who want to centre text, add an image, and italicise a bulleted list. That's all there is to it.

You're being very nice with your 5th version, but the real developers will just go elsewhere in the medium term.

En bref : ok Ckeditor : vous faites un truc comme $('textarea').html($('textarea').text()), mais honnêtement on s'en fout....on a jamais souhaité ça

[mischabraam]

EDIT : config option versionCheck: false Fixed 🥇

            extraPlugins: "youtube"

[Jean-Gian]

@DMeloni i totally agree, but I'm being even more pragmatic here. Depending how much the license is, it might be more convenient to pay for it for a period of time while implementing another solution. This doesn't mean giving in to blackmailing, but just making the most sensible choice we might have in the short term. About blackmailing, yes, they are doing their best to get more money they they can, and the behaviour is deplorable. I've been in contact with them but they won't tell what the price is. They are trying everything to understand how badly someone needs a license to adjust the price accordingly. Horrible

[Jean-Gian]

Are you all ready to laugh? I got a reply about their license prices and i quote:

The minimum subscription fee we do offer for CKEditor 4 Extended Support Model - Security Vulnerability Assurance: $9,400 / year. This fee covers up to 250 users of CKEditor 4 across your client's applications and guarantees that we will deliver security fixes to CKEditor 4
