Support » Allgemeine Fragen » no access to plugin page in backend

  • Hi. I don’t know if my problem is caused by a plugin (events manager) or if there is a general problem.

    i updated a plugin and now the specific plugin isn’t working anymore but furthermore I can’t see any of the other plugins. there are still all plugins installed (and working), but i don’t have access to the plugin page in the backend.

    (the frontend is working so far, despite the content of the plugin.)

    i would be thankful for any idea how to resolve this problem.
