The font also appears larger in the history and the text overlaps (example from Wikidata). Could it be related? I only see this when I'm logged out.

@Aklapper the languages ​​appear normally for me, but when I click on "Search for a language" and write "Spanish" or any other language nothing appears. The gif I added shows this.

@Aklapper I updated the description. Is it better understandable now?

@Aklapper: yes, logged out too.

@Lucas_Werkmeister_WMDE: the T340859 error only pops up for me when I activate the DuplicateReferences gadget. A recent change made mobile and desktop gadgets available by default, causing errors.

"Sitelinks" has been styled similarly to the desktop version. Screenshot below:

It returned to normal

I see this same error all over the pages of people like Bill Gates and Elon Musk.

Thank you very much @ovasileva and @Jdlrobson. Sorry for the delay in replying, I was on a wikibrake.

@DLynch Yes, but currently it hides the return to talk page button.

@Superpes15 thank you!

Returned to normal

@Aklapper I made an edit on the English Wikipedia and the icon still appears. This was also reported here.

@Jdlrobson Hi. Sorry, I thought you could see the picture.

@Whatamidoing-WMF I think so. This is affecting multiple pages, not just talk pages. See the MediaWiki home page

I'm canceling this task. Thanks for the information @Bawolff, I will use another alternative.

I found a code review.

Thanks @Zabe. I didn't understand how this extension can be useful in all projects...

The error appears in Google Chrome and Opera. I haven't checked other browsers.

done. It's working correctly.

@Stang @Lucas_Werkmeister_WMDE Not showing icons was a choice, but I can add them if needed.

@Stang thank you so much!🙃

@Stang Yes, exactly.

@Stang: The order of the tabs must be changed. "Categories and pages" should be the first. See: T284208 by @Seddon

Hi @Stang! Yes, it currently only has three local files. Thank you so much for working on this task.

thank you @matmarex

@Juan90264 thank you so much

thank you so much @Juan90264

@Aklapper done: T294691, T294690

I'm canceling the task. See T292806

@Bugreporter ok, so we can substitute the importer group for transwiki importers, right?

@Aklapper Hi. Images on smaller screens are centered by default. This error only occurs in Meta, so it must be related to the task informed above.

@matmarex thank you very much!
