What to do if you get fatal errors when using the Sharing Cart or Project Course Format
These errors are likely due to third-party modules or incomplete installation of LMS program files. Here is a sampling error reported by one user of the Project Format when restoring a section of their course.
Fatal error: Uncaught exception 'SharingCart_ModuleException' with message

Our programmer says he has seen this happen before, and it was something occurring outside of the Project Format/Sharing Cart which was breaking backup or restore. The PF/SC both operate with the standard LMS code for backup and restore. In the previous case, we speculated that it occurred due to one of the following reasons:
- an incomplete installation of the LMS program code
- a database problem/corruption/incompatibility
- a third party module that is breaking backup or restores (may have no backup/restore function, or may not be up-to-date).
Most problems we have seen are related to the third one. You might try doing some of the following:
- turn debugging on to ‘All’ or ‘Developer’ level and see what error messages you find
- try doing the standard backup and restore of a course and see if the problem repeats itself
- see what type of database you are using and version number
- tell us what third-party modules you are using and we can tell you our experience with them
- set up a new LMS installation with no third party modules and set up PF/SC to see if it works–then add modules one by one, testing backup and restore
