I can't create categories in my posts. All of my posts goes to uncategorized category even if I tried to create category in the categories area. The weird thing is, if I search for a category name, there's no result but if I add a category name which already exist, it says "The category you are trying to create already exists."
All of my posts are categorized so that it would be easy for me to control what posts I would like to display.
Does the web hosting has something to do about this? Thanks
