Hi
1-some of categories can not be deleted. I did everything but still can not delete them. one of them had some jobs so it can not be deleted. I deleted the jobs and the category deleted easily. BUT there is a category that is empty and unpublished but can not be deleted!


2-I created some categories and revised their name. now I got "Requested page not found...!" !!!!!
I deleted an created the same name categories but still the same problem. even I added some jobs but nothing changed....

I am using SH404sef component to rewrite URLs. some of categories(with or without jobs) are working as charm. but some of categories are not available with this Requested page not found...!" !!!!!

I disabled sh404sef but still the same problem.
I dont know what to do.
Thank you in advance

I added a subcategory to one of the categories that I get display error and amazingly the subcategory is working but the main category not working !!!!!!!!!!!!!

I found a solution!! 
I renamed the category and it worked but again I changed to previous name it is not working again..
