Yesterday, I updated MOODLE version 1.9 to 2.5. I did this using GIT and went in successive steps (1.9 → 2.0 → 2.1 → 2.2 → 2.3 → 2.4 → 2.5). After each upgrade iteration, I would check that everything went okay (i.e., courses still work, links, blocks, etc.). I had to make a few adjustments such as upgrading assignments, plugins, etc.) I have managed to resolve all but two issues.
- One issue now resolved is that my domain name is on a different server and was forwarding with masking to my moodle sub-directory on a dedicated server. I noticed that this produced a blank page in version 2.5, since the default setting is to disallow moodle to be embedded within a frame. I was able to remedy this by forwarding the domain without masking.
- All courses appear to have updated successfully; however, there are a few courses that display correctly but cannot be backed up. The error message displayed is "
Error writing to database
Clicking on the 'More about this error' link shows:
error/moodle/dmlwriteexceptionThis indicates that a general error occurred when Moodle tried to write to the database. If you turn on Debugging you will get more detailed information about what the problem is.
- The other issue involves update notifications for both Moodle and for plugins where I receive the following error message
Unable to fetch available updates data - unexpected cURL error.
I do not see specific curl error messages displayed with debugging turned on.
While I have resolved the first issue, I am unable to workout solutions for issues #2 & #3. I have turned Debugging on up to but not including Developer level and have checked all the boxes on the Debugging page. I do not see any errors displayed. Perhaps I am looking in the wrong spot.
If anyone has suggestions, I would appreciate it.
