Trying To Add New Categories To Blog But Getting Could not insert term into the DB...

Hi there,

On my Wordpress blog I'm trying to add some categories but every time I try adding one from the Add New Post page it seems to accept it but it never appears in the category list.

I've tried going to the category section direct from the Wordpress admin area and added the category this way but it brings up an error in red text:

Any idea what the problem is?


Thanks for any help

 

Is anyone able to help out or offer any advice on how to solve the problem?

I've tried deleting categories and this is fine but when I go to add a category it just says: Could not insert term into the database

 

there might be problem in some plugin... deactivate all the plugins and try to add category...
