I updated to SPPB 5.5.0, and now I'm getting 100's of the same PHP error. See hidden contect for details.
I've already tried installing per Toufiq's recommendation at https://www.joomshaper.com/forum/question/37604#qa-answer-183132, but the proposed solution had no affect.
See www.certifiedinfosec.com. Google inspect shows tons of errors too.
