What does your mod_wsgi configuration in Apache look like?

Is the mod_wsgi you are using definitely been compiled for Python 3.9?

This issue may be caused by one of the following:

* A permissions issue where the directory/files for the Python virtual environment are not all readable by the user that Apache is running your code.

* Your mod_wsgi is actually compiled for a different Python version than the Python virtual environment was created for.

* You are loading PHP into the same Apache instance and PHP is preloading an image library (which prevents PIL loading version it wants) with version which is incompatible with what the PIL image library is expecting. This causes import of PIL imaging extension to fail.

I would actually speculate it is the last one, so if you have PHP loaded into the same Apache instance, disable PHP so it is not loaded and see if the issue goes away.

Otherwise ensure you supply what your mod_wsgi configuration looks like and what version of Python mod_wsgi was compiled for.
