Hi guys,
I moved my modx revolution to a live server. I dumped my database to the new one, then install Modx revo by choosing the "upgrade" option. After re-installing the snippets the page is rendered correct (except charset?!) but when I am in manager I couldn’t see the settings (system and all others e.g. tinymce). Its loading and just stay blank and says: no data to dislay. I google a lot and checked all pathes and htaccess, but nothing helps. the tinymce is also not used in backend

Did something went wrong with my move to server?
is there maybe a how-to for modx revolution, as I couldn´t find one.
thank you a lot and greetings!
