I have installed helixultimate_quickstart_j4_v2.0.11 successfully and everything works. I paid for the business package of SP Page Builder Pro. I downloaded com_sppagebuilder_pro_v4.0.5.zip. I went to System>Extensions>Upload Package File. I uploaded the com_sppagebuilder_pro_v4.0.5.zip and joomla reported it installed without error. When I go to the site now (front end, like a public user), I get the error page with the error image and error number is 0 with message of syntax error, expecting ')'
I have deleted my database, started completely over. Helix works fine, I can customize the default templates fine and create templates with SP Page Builder lite. Soon as I try to uplate the pro component, it breaks something somewhere. (thankfully there I make backups).
I cannot see any other way to enable the pro features and when I try to download anything with the "Pro" label on it, it simply tries to sell me the package again.
Tried the chat for help, guess that's only for pre-sales...they told me to come here for help.
