good afternoon I get this error when trying to enter to the tags of the backend and the other options under control panel, articles, comments and categories, I'm going with the manager that I've always gone in and not had problems until days, I also said: You are not authorized to view this resource. I made some modifications to the code of the front end where users create articles. it will have something to do for me to leave this error? someone knows why this happens? Greetings and thanks sorry for bad writing in English
