SPPB Layout "Blocks" not able to load

Hello. It seems that even though there is one installation on my server that is properly loading the Layout blocks within SP Page Builder Pro... for one single site, it is not working. This is a new post being created as requested, to ask for help and I can confirm that if it's the cache file size, then it must be something causing it for a folder because there is another SPPB install that does work. I'll send the details!
