WProofreader Plugin Issue

Same problem for me with same config.

In the Full HTML text format I disabled the WProofreader button and the CKEditor now loads (it did not before).
This fix worked on 4 separate sites on 2 servers with different PHP versions.

aitala thanks for your info.

Hi,
The error is a result of WProofreader plugin incompatibility with latest CKEditor 5 version (v45).
Attaching a patch with an updated WProofreader version. The patch has to be applied on drupal/ckeditor5_premium_features

Tried patch, got same error.

The patch solved the issue for me.

Thanks.

@salmonek I'm getting the same error and I don't have the ckeditor5_premium_features module installed. I believe there should be a different fix/patch?

Just add this within composer.json patches section and it should work,

"drupal/ckeditor5_premium_features": {
                "WProofreader Plugin Issue": "https://www.drupal.org/files/issues/2025-06-23/3531493.patch"
            }

ckeditor5_premium_features is a dependency module that is installed along with ckeditor5_plugin_pack so it is already there. You can see it in the lock file if you want to check. So just add the patch to your projects's composer.json and it will patch the ckeditor5_premium_features module.

@aitala
Please try updated patch (cache rebuild required)

@carolpettirossi
Exactly as @chike said premium_features is a dependency for a plugin_pack. In case of Plugin Pack WProofreader installation also PF WProofreader is being enabled and the script is there, thus the patch is for Premium Features module.

Ok, re-rolled patch seems to work.

Thanks,
Eric

I applied the patch (3531493_9.patch). The WProofreader functionality has been restored.
Thankyou

Facing the issue

Moving to CKEditor 5 Premium Features

Attached a static ckeditor5_premium_features--2025-06-28--3531493--mr-30.patch file, for current point of MR30.
To be used with Composer Patches.

in js/build/wproofreader.js there is a console.log instance returning output whenever the CKEditor loads. Not sure if this is intentional.

console.log(Object.prototype)

Me too.. It is in #3 and #9
Noticed the console.log(Object.prototype),Object.prototype.hasOwnProperty.call(this._userOptions,"autoStartup") it was not in the old script.
Not sure if the build was with a dev option, orif it came from the
Also found in
https://github.com/WebSpellChecker/wproofreader/blob/master/wscbundle/ws...

Pushed:

• build without console.log
• sources form https://github.com/WebSpellChecker/wproofreader-ckeditor5 (we use that one, not wscbundle)
• old build for compatibility with CKEditor 5 older than v41.0.0
• hook_library_info_alter implementation to change to old build file reference in case it is needed

Not sure how this log ended there. It's not in the sources and I do not remember adding it manually (however this seems most probable).

We're planning to release it tomorrow.

Code was merged and released in version 1.5.0

In case you use some of premium plugins other than WProofreader please note that we changed our third party composer requirements to suggestions. Depending on used features some packages may need to be manually installed after update to version 1.5.0.
