Help fix Worpdress blog categories, exchanged with 1 100-directory submission package

After doing accidental categories to tags conversion and revert back, now some of my categories are hidden - cannot be shown in Manage Categories, but there in write new post.

I noticed the double slash // before the category's name.
Ex: //vidoe

try changing the theme
look at your htaccess file

 

You need some special treat to your .htaccess
if you need me to do it for you,then PM me..

 

I have changed through a few themes, but the only category in Manage Categories is Uncategory! The rest can only see while writing new post!

 

There must be a database problem.

 

Use the database manager plugin, and repair your database through that. Also in cpanel, you can do that but I never found that quite reliable always remember, back up before you fix/change anything.

 

Cz' i used to convert cat to tag, there is post_tag for category name. After changing, they all works fine now. Thanks for your great help, dudes.
