I have a fresh installation of Kreativa Quickstart package on a local computer.
The front end works fine.
Most of the back end is also fine.
But the server is returning an error 500 on all items except one under the SP Page Builder Pro menu, i.e. Pages, Media Manager, Easystore and Settings. (The Categories item does not get an error.)
Are there any log files I can look at to give me more information?
Background: I installed HelixUltimate on this server, in a subdirectory of the web server's root folder. This is working without errors.
Then, I installed Kreativa (kreativa_quickstart_j4_v1.0.1.zip) in another subdirectory of the web server's root folder. I am running Apache/2.4.52 on Ubuntu 22.04.3 LTS.
