Hello experts, I have a problem. We have our Brazilian Jiu Jitsu and Kids Martial Arts menus under our "Classes" menus that result in a 404 error. I am not sure how long this has been going on, on our Joomla 2.5.6 site but I must fix it pronto. I see the kids article is a single article that exists. I see the BJJ and Striking menu is linked to a category that exists. Do you guys have any idea how I can fix this?? Thanks so much!
