#870 –  Error Call to undefined method Joomla\CMS\Application\AdministratorApplication::getLanguageFilter()

We cant save any articles in Joomla without this error.
This happened after the update.

Hi Elisabeth,

Just tested under Joomla 4.1.2 and I cannot reproduce this issue. What other third-party extensions are you using? What's your PHP version?

Regards

Did you see I wasnt the only one with this problem?
I am using PHP 7.4 and I use quite a few third party extentions on the website Dolcevia.com but I doubt they are to blame. It defenitely happened after I upgraded your extention.
I have a website that has yet to be upgraded to your new version. Would you like to login there are try and update it yourself. Maybe you will see a clue as to why this is happening.

I did see that other users reported the same issue. I am not asking in order to blame other extensions. I am asking because I need to reproduce the issue in order to fix it. And under my sites it works perfectly at the moment.
Yes, if you could provide administrator credentials that would be fine. Just make sure that you create a new private ticket for this.
