Is it possible somehow for MODx manager to not be able to display content from the database??? Front end is fine - DB seems fine. But in the manager - resources list empty, elements list empty, system settings empty - even Reports > System Info database info is empty.. see attached... ?
Just upgraded to 2.3.1 and still the same issue...?????
ok - cleared all caches and bang it appeared... odd! but glad all sorted...
I'm glad you got it sorted, but definitely upgrade the site. Cache corruption was more common in the early 2.x versions and several serious security vulnerabilities have been fixed.
I recommend the UpgradeMODX extra.
Upgrade to 2.4.0, then 2.5.0, then the current version.
