Ahoj,

It looks like a preloader problem from template, SPPB works OK.

but I will check

Site is working now.

But there is conflict between Securitycheck Pro settings and Template Preloader. I had to disable preloader which you de facto you don't need, your site is fast. Preloaders were popular in last years, now they are used very rare becuase of Google rules and internet is faster in EU/USA

Ahoj! You are very fast today :-) Thank you very much for help - everything worked until the update. But you´re right, I don´t need preloader..

Thank you and have a nice day today, tommorrow and the rest of the year :-)

Robert
