Same issue as : https://www.joomshaper.com/forum/question/20091 .
After attempting a test upgrade the site went down with this error.
I agree with one of the comments left in that post. If an actual answer had been posted there I would have been able to deal with the issue myself rather than bothering you guys and/or waiting for a reply.
Please assist.
Joomla 4.4.7, PageBuilder 5.3.6.
Note that the folder: public/administrator/components/com_sppagebuilder/builder does not seem to exist, so thre is no way that builder/classes/base.php could have been loaded.
I had installed the latest version vis system->install->extensions from a download from your site.. so perhaps your installer is broken?
The Helix updates were nstalled by the Joomal automatic installer (system->extensions->update) BUT... when installing I got these messages:
This extension does not provide a checksum for validation of the integrity of the downloaded file.
JInstaller: :Install: Can't find XML setup file.
Before updating ensure that the update is compatible with your Joomla! installation.
You are strongly advised to make a backup of your site's files and database before you start updating.
Thanks
Chris
