I just installed a new web site with the JD Ohio quickinstall.
The website adress is www.sefasham.com
Installation worked fine.
After installing I tried to update joomla wich was 3.7 to 3.9.3 actual version.
And then I got this message:
Fatal error: Call to undefined method JAdminCssMenu::addChild() in /homepages/3/d751282266/htdocs/0Sefasham/administrator/modules/mod_sppagebuilder_admin_menu/tmpl/default_enabled.php on line 16
