I'm setting up 2 localhost-only wikis for development purposes and
trying out new ideas. One called 'wiki-drugfacts' and the other called
'wiki-tgmeds'. They both share the same mariadb database although
'wiki-tgmeds' does have a prefix of 'tg-' first in the database.
whilst endeavouring to set up 'common.css' like I already have on my
main 'DrugFacts' website, it is working on 'wiki-drugfacts' but not on
'wiki-tgmeds'. It seems very likely that I have set up
'http://localhost/wiki-tgmeds/index.php/Common.css' but now I can't
delete it. So how can I securely delete it please?
I've looked at these pages , , and  and they all seem to imply
that I need to be in the 'administrator' or 'sysop' user groups. so
looked at all possible variations of user/root setup of wiki-tgmeds to
see if I can change the user permission for myself, but without any
success at all.
I'm now coming to the belief that it possibly relates to how I set up
wiki-tgmeds. I set up wiki-drugfacts and got it working as I wanted, and
then I created the wiki-tgmeds directory at /var/www/html/wiki-tgmeds
and then proceeded to manually populate the directory with an install of
the mediawiki files, from when I expanded and extracted
'mediawiki-1.31.0.tar.gz'. I found the site on localhost in my browser
and then just proceeded to create a new 'LocalSettings.php'. And once
the site was up and running I created one article but wasn't able to get
the text to wrap around the TOC, which started me off on my quest to get
'Common.css' working properly.
So to recap, how can I delete the erroneous 'Commons.css' file on wiki-tgmeds'
