I am a new user of moodle, and I am trying to create a educational platform. I currently using the free version of moodle so I can test the features and after trial period finish buy the license. My problem is that I am trying to upload a theme from plugins, but the "Install plugin" button doesn't appear on the "Site administration". I am the only super admin in the forum. I have seen some similar questions and in most of them the answer was to be sure that you viewing with super admin view (but I am sure that this isn't the problem).
I have hosted this site to moodle official server. After searching and many re-installations of the platform, didn't manage to find out what is wrong.
Does anyone had the same problem and found solution?
