Will my moodle site find this upgrade acceptable and keep chugging along? Is there something extreme I should do (besides regular backups) to be prepared?
Any advice would be appreciated!
Many thanks for the heads-up on that! So, if I see similar symptoms, I should use phpMyAdmin and set text fields default value to NULL?
How often did you see these errors?
Again, many thanks!
No we got those error messages in normal view (and by turning debug on we found out where they came from)
Another error that we encountered, but for which I did not found an easy solution (until now) is that in new courses that start using graded activities the gradebook wishes to fill in 100 as weight while the weight column in MySql only accepts 99,99. I worked around this by inserting manually an entry into MySql for each course ID in which this problem occurs, but that was not ideal.
I just now found the answer here: http://moodle.org/mod/forum/discuss.php?d=41501&parent=190748
