Description of issue
After Upgrade any Version of the OJS 3 System to a next version, the frontend and backend of the system are displayed totally broken (this happens only in a browser that has the pre updated version of the OJS cached). After clearing the browsercache, everything is fine.
How can this be prevented? When our editors and users see this, their first impression of the system is “Hey it’s broken” altought everything is okay.
I would be grateful for your help.
