1. SP Page Builder 3.x
  2. Friday, 15 November 2019
Hi there,

I have updated to Joomla 3.9.13. The update was successful.
After that, I could not get into the backend, after login as administrator the site throws HTTP error 500.
I contacted my host and he provided me the following detailed error message:

PHP Fatal error: Call to undefined method JAdminCssMenu::addChild() in /home/www/web47/html/dani_neu/administrator/modules/mod_sppagebuilder_admin_menu/tmpl/default_enabled.php on line 16,

Can you please help?

Thanks in advance.

probably you have OLD SPPPB Inside, which you forgot to update first.
Step #1
DELETE this folder:

Step #2
Update SP Page Builder to v3.6.x
If you don't have access to updates, just disable SPPB Admin Menu module (!)

Step #3
Update all extensions which need an update, also JCE editor

Please follow these steps:

1. Use FTP tool and delete folder: administrator\modules\mod_sppagebuilder_admin_menu
2. Update SP Page Builder to last version (if you cannot, copy this folder from last version of quickstart)
