Hi there,
I want to clone a working site but I receive the error "Error 0 path cannot be empty" when I try to access some of the Virtuemart admin pages and I have the same error if I try to access the site front end.
The admin pages effected by the error are
Control Panel
Configuration
Product Categories

I copied all the files and tables from the original working site to the new one.
I changed the settings in Joomla configuration and fixed the safe path setting in the virtuemart config table.
Both sites have the same php version (8.3.11)
Joomla version is 4.4.9
Virtuemart version is 4.2.4 10922

The Joomla debug shows the following:

Delete all folders inside the "cache" directory at your site's root.
