Hello,
I am using the current template themis 2.0 with sp page builder 3.8.9 on Joomla 4.2.6.
Again and again some pages are not loaded, only after a refresh (F5) they were displayed.
Since I am not the only one with this problem, I have searched a lot in this forum.
Ultimately, however, the problem was the preloader, which I simply disabled.
My solution is a top line in customer.css:
.sp-preloader { display: none !important; }.
Maybe it helps one or the other to save time ;)
