Hello all I have faced some problems after upgrading my Wiki from v.1.20.6 to v.1.22.13

All tables that were collapsale stopped working, I used to do so:

{| class="standard mw-collapsible mw-collapsed" style="text-align:center; margin: 1em auto 1em auto; width: 760px;"
|-
! colspan="5" style="background-color:#f7e9d4;"|Table
|-

And now it doesn't work. I tried other options like discribed here https://www.mediawiki.org/wiki/Manual:Collapsible_elements. I did so:

{| class="mw-collapsible mw-collapsed wikitable"
! The header || remains visible
|-
| This  content || is hidden
|-
| at first || load time
|}

So and this version didn't gave me a result ( How can I fix it? So there aren't any hide/expand buttons (

Here it is the link with test page with tables: http://www.wikijournal.ru/index.php/Test

What should I change there to make a table collapsable?

You have Extension:Vector installed, but your version is 1.22, and Extension:Vector is already part of core MediaWiki since 1.22. You should remove it because it causes JavaScript errors preventing other things to load properly (maybe related to your Editor problem).

Thank you! Yes it can be a reason I will remove Vector extension and let you know if it helped )

You were right. This bug including problem with WikiEditor was due to Vector extension to be connected )
