Tiki 24.2 image load generated 500 internal server when not logged in
I did a clean install of Tiki 24.2 on a shared server. The server is configured with the following versions:
- Apache Version 2.4.55
- PHP Version 7.4.33
- MySQL Version 10.3.38-MariaDB-log
The install and import of my database from Tiki 24.0 which was upgraded throughout the years going back to Tiki ~15.44 proceeded without errors.
Now, on my HomePage, images take a long time to load or are more likely to generate a 500 internal server error.
When I login as admin, all images load quickly and I don't see the 500 internal errors. I've run sh setup.sh and used the default permissions.
This seems like a permission problem but I don't seem to be able to find it. Would someone suggest a solution or a way to troubleshoot this?
