PROBLEM UPGRADE SP PAGE BUILDER

Dears,

I tried to do following action:

1. Increase your PHP version to 7.2 or 7.3 (suggested).
   I have 7.4
2. Update Helix template framework to the last available version.
   I installed the latest from your website '2.5.8'
3. Update JCE editor to the last version. It should be at least 2.9+.
   I don't know where I check it
4. You have delete all php files from folder:
   templates/your_template/html/sp_pagebuilder
   I have not this folder!!!
5. Check addons located (overridden) inside the template directory:
   templates/your_template/sppagebuilder/addons

• maybe one of them use old version of code (from SPPB 1 or SPPB 2), which is not supported by SPPB 3 anymore.
  In that case, you should:
  ask your template developer for an update
  or
  delete the broken addon folder manually.

I don't kno what are the addons not supported, I have found these addons:

I cretate a superuser if you need it:
