 * Hello,
 * I´m following the advice from Marko Vasiljevic: “… reach out to your theme support
   and check with your hosting support also, to resolve these errors. It appears
   that there was some problem with the theme and the PHP update or similar.”
 * I did a major update of my website in this running order: plug ins, word press(
   to last version) and php (on domainfactory.eu) to V8.2.
 * After that I received the white screen, an error message about W3TotalCach and
   couldn´t log in any more.
 * My pc runs on windows10 and the browser is Firefox.
 * After all this I got in touch with Marko and did following things:
    - deactivation of all plug ins
    - deleting anything being connected to W3TC
    - deleting HTAccess lines being connected to W3TC
    - starting debug mode
    - switching back to php v7.4
 * Now I can see the website (very deranged), but still can´t log into the dashboard.
 * Following to Marko I would like to ask you for further support as this situation
   is taking a lot of time and energy. I am absolutely not very experienced, so 
   please take that into account if giving me any instructions, so I can follow 
   your thoughts realizing those steps!
 * Thank you very much! I hope you can help me on this, Gr. Uwe
