Hello everyone,
we're having a major issue with the administration in the X3 Pro system. My 13-year-old son has been publishing his photos and articles without any problems for about five years.
Yesterday, my son came home upset because, although the website is working, the admin panel isn’t working at all, and he can’t add new content or edit old content. I found that after logging into the X3 Panel, the folder structure (left menu) doesn’t display. When he clicks on the folder list, the window turns gray and nothing happens. You have to refresh the page. System functions—Settings, Tools—all work. For example, you can change the template and design.
I thought maybe something had broken (or rather, that my son had done something he shouldn’t have), so I restored the entire website from an offline backup. Still the same behavior. I updated X3 to the latest version. No result. I upgraded PHP from 5.5 to 7.4. Nothing. I performed a completely new, clean, full installation using the X3 installer. The installation went OK, the diagnostic script reports no errors, but the behavior is the same. The front-end works, but content management does not work at all.
I don’t see any abnormalities on the server, and I haven’t received any information from the provider about changes made to the configuration. But of course, I can’t rule that out. We’re just users.
Please, do you have any experience with this behavior? Do you have any ideas on how to resolve the situation? My son is desperate, and it’s really bothering him.
Thank you very much for any response. Jakub Sr. & Jakub Jr. (Sispunda)
