I have upgraded to v2.1 and now none of my categories are showing in any templates. I am running mysql 4.1.20 and have tried searching but haven't been able to find a solution.
I have tried everything I can think off. Disabling all plugins, adding a new post and selecting all the categories, manually looking in the database, using the default theme, etc.
Does anyone have any ideas on what else to try or how to fix this?
