Hi Pat,
it looks that was problem with folder permissions and component files were not uploaded/updated correctly.
The only way to fix it - is thru FTP
- Download SPPB Pro 5.0.9 package (com_sppagebuilder_pro_v5.0.9.zip)
- Unzip
- Using FTP upload all folders & files from /admin/ inside that folder: administrator\components\com_sppagebuilder
- Then do this same with /site/ - but this time here: components\com_sppagebuilder
yes, override all files inside (!)
then try to install SPPB 5 again in normal way.
