I hope it is okay if i continue in this older thread. I am encountering the same issue with one of our Journals (OJS 3.3.0.13, but originally setup with 3.1.0.1 and updated to many versions in between). The checkbox to enable the usageStats Plugin just remains grey and can not be clicked, even when logged in with the admin account. Therefore i was wondering if you found a solution for problem @juanito ?
Yes, i actually got it working like this – Thank you! I do feel like having to edit a source file is maybe not the best “final solution” though. It seems to me, like this might be some kind of bug. In OJS installations that started off with a later version this plugin is enabled by default and can not be enabled. The check seems to ensure that you can only change this setting if you’re not in the context of a specific journal; but i was not able to find a site-wide config menu for this either. Anyway, now it works!
