This is a real issue: I have had this problem in all versions of CMSMS from 1.0 onwards that I've used.
I've never solved it. Usually not touching the site for awhile, it seems to resolve, but that doesn't work for my clients
No error logs are ever produced.
It happens on many different hosting environments: windows, linux, etc. (yes, I run the CMS on a windows machine! for one client. It's crazy.)
I've even tried restoring a backup database to fix it.
The only thing that ever seems to fix it is time.
Would be nice to someday see why this is happening.
Systems I've had an error on:
Linux & Windows based CMSMS installs, from version 1.0 to 1.5.2
Solutions I've Tried:
Clearing cache
Changing File unmask
changing content type
using a different template
deleting/re-creating page
clearing cache by deleting files via FTP
setting entire site to 777
checking logs
turning debug on
None of this has worked. None of this has even shown a single error.
What has worked:
Waiting random time periods. Until it starts acting up again....
I also try using different machines/browsers, & that seems to work. I think it's an issue with the javascript breaking. However I haven't been able to test that.
Next time you get the error, try debugging the javascript if your browser supports it. The problem with this solution is it's typically my clients who see the error & they aren't running javascript debugging. The times it's happened to me I didn't think of it in time.
