I do have a problem with cathegory blogs. When I open an article with the "read more"-button then every module from the previous page is still visible. (for admin: for example have look at the cathegory blog Team on the homepage)
This issue causes only with cathegory blogs and only after a certain time. When I restore a backup then the issue seems to be solved but after about an hour it happens again. I hope it's a user error :-)
Thanks for your help!
