Thread:Project:Support desk/ResourceLoader module Error/reply (2)

Thank Florianschmidtwelzow for answering. I warn you that I'm new on MediaWiki :D... I didn't imported old extension and i have no package in my Debian installed as extension of mediawiki. When i uploaded my mediawiki i just removed the old folder /usr/share/mediawiki and put the new MediaWiki 1.25. Then i putted in the new folder of mediawiki (/usr/share/mediawiki) the old logo and the old LocalSettings.php. There are old files also in the folder /etc/mediawiki that i didn't change.
