I have three seperate blogs running off the same template. I have noticed that on one of them the 'categories' and 'tags' widgets are not displaying. I get an <h2> title header but nothing else. This only happens on one of the blogs and the other two (which use the exact same template) are not affected by this problem.
I have tried switching themes to see if it was database related and both categories and tags display fine using the default theme. I deleted and re-installed the theme and nothing changed. I've also tried deleting and adding the widgets again with no success.
If anybody has any ideas I would be really grateful for any help!
