The file referenced in the error message appears to be encrypted but the first line makes a php call to check the ioncube loader - is this likely to be the cause of the problem?
This website was created on a local test site, backed up and restored to the live host. Could this discrepancy between the origin site and new site be contributing to the problem?
Everything else works as expected so it is strange that I am only getting error messages in Media Manager, an area which I wouldn't have thought would have links with CBSubs.
I really have hit a wall with this so any help no matter how small would be appreciated.
