I have been trying to set up a College-wide Moodle site using v1.8 with MS SQL.
Every time any course creator adds more than ten resources to a single course, all the labels to resources disappear and the resources are no longer available.
If the eleventh resource is removed, everything goes back to normal.
I had a similar thing happen with the number of courses in each category. In this case the new courses don't appear, but are obviously in the database somewhere, because it won't let you use the same course name again.
Does anyone have any idea why this is happening?
