I have two installations of OJS 3.0.0-0. One works fine; but in the other, TinyMCE is MIA. On pages like Journal Settings, the long-form text entry areas like “Journal Summary” just have a big blank space.
The HTML to trigger TinyMCE all appears to be there. The TinyMCE JavaScript components are being downloaded, both according to the browser network monitor and the server logs.
Does anyone have any suggestions as to what else might be different between the two installations? I’m really at a loss.
