After the upgrade to SP Pagebuiler Pro 3.7.8 my frontpage crashes if i drag some slideshow blocks into the page. Not all of them, but a lot are giving the same problem. (Also the slideshow with videobackgrounds blocks)
After that only the header and footer of the page is visible and the page can't be edited anymore. (broken)
After that i tried a clean install of the latest Joomla, Helix Ultimate and SP Pagebuiler (php 7.3.21).
I tried other templates and PHP versions. Still the same problem, so it must be a bug.
You can try the "The Amazing Slideshow" (blue person) and see for yourself.
