I just wanted to update to the latest version of pagebuilder and got this error:
Failed opening required '/var/www/vhosts/<domain>/httpdocs/administrator/components/com_sppagebuilder/editor/helpers/AddonsHelper.php' (include_path='.:/opt/plesk/php/8.3/share/pear')
I tried updating first with Extension-Update mechansim (from V4.0.7 to 6.1.2) and then tried to upload the whole zip-package. Both would not work. With FTP I see that there is not com_sppagebuilder/editor-directory at all...
