I'm not sure why this happens, but the webhook on this extension causes an unknown error to occur when publishing an edit through the VisualEditor. This is more of a luxury extension for me, so I did not dive into the issue, but thought it was worth mentioning.
Breaks Visual Editor
Thanks for notifying about this! What mediawiki and VisualEditor version do you have installed? Did you get any errors on your PHP log file? I'll try to reproduce this error in the weekend.
I am running Mediawiki Version 1.28.0 and VisualEditor 0.1.0.
This was in the process of migrating to a new install and I did not get any errors in the log file, but if needed, I could recreate the status and change the log level to debug.
I can however tell you that the edit was actually successfully recorded and the error occurred between the clicking "Save Page" and the pop that says your edit was successfully saved.
Let me know if I can help diagnose the problem further.
I've pushed update which fixes the extension breaking with deprecated article saved and inserted hooks. It would be highly appreciated if you could pull latest version of the extension code from github and let me know if that fixed it for you :)
Unfortunately, it did not fix the issue:( Also, i checked the log files and it is not recording any errors. Here is a screenshot of the error I get.
OK - Taking a look now.
Reproduced the problem. The problem with this issue is that is does not generate any log in the php, apache error log files nor chrome console. I couldn't even find that error anywhere in the visualeditor sources directory. I'm adding bug report of this in visualeditor extension talk page as this seems like visualeditor doesn't really work with extensions that also use same hooks that it uses.
FYI; I did not test this with latest visualeditor master branch to see if this issue was resolved there. Master branch requires MediaWiki > 1.29, I have 1.28 so cannot use that.
