I have 500 internal server error problem in some pages of my site. Especially in some categories, when i click them they won’t open. I can’t even create categories with specific names. For example when i try to create a category like “abc”, Wordpress creates a category url like “www.mydomain.com/category/abc”, then i add posts it works but when i create a category like “def” , Wordpress creates a category url like "“www.mydomain.com/category/def” and it opens as a blank page (as there’s no posts assigned to it) but when i assign some posts to it and click it says 500 Internal Server Error.
I have this problem with categories
I tried everything;
- All deleted almost all of my plugins (and i wasn’t happy to delete the ones i love very much)
- I optimized databases
- I did everything with htaccess file (deleting, renaming, recreating etc.)
- i increased php memory limit in wp-config file. (and i memory plugn says i use only 30-40 mb of memory, there’s no memory usage limit exceed)
- i used cache plugins
Nothing works, please somebody help me
