Trying to hide the left sidebar, I accidentally changed the Vector CSS rather than the Common one. Now I am unable to edit the custom CSS page for some reason -- when I go there, the text appears but is not in an editing window, and there is no save button.
Help?
Easiest solution: In your user preferences, change the skin, which your user account uses, to Monobook or so, essentially to anything that is not Vector. Then fix the page, e.g. by going back to an older revision and switch the skin back to Vector.
Some way more difficult solutions would be this: If you have direct access to the database, you could fix it by manipulating the conents of the Vector.css page inside the database. Apart from that it will be hard to guess what you have changed (and so what you would have to change back, e.g. using Firebug) in order to make the editing field and the button visible again.
I'm sorry, I can't figure out how to "go back to an older revision". There is no link or button for this...? When I try to "change visibility of selected revisions" I get:
Revision visibility could not be updated:
Error hiding the item dated 18:30, 23 September 2016: This is the current revision.
It cannot be hidden.
There is no delete button. Thanks for your help!
It is way easier: Just go to the revision history with action=history in the URL. Then check the different revisions and find one, which did not have the problem. Then hit "Edit" and save. This will effectively roll the page back to that revision.
But you can also choose any other way to go to an older revision - the point only is that you again put content on the Vector.css page, which does not cause the problem.
Oh NOW I get it! Before I modified the code, I could just enter something in the text window. Once I saved it, it created an edit link in the top, but I never saw it. Duh. It just never occurred to me that this was a page like everything else.
Thanks for your help ;=}
