Saw a previous closed post that sounds similar to the issue I am having. When upgraded iRedAdmin-Pro-SQL-4.4 -> 4.5 I get an internal server error when trying to access iredadmin

Log extract from apache error.log:

SyntaxError: invalid syntax
mod_wsgi (pid=62289): Target WSGI script '/opt/www/iredadmin/iredadmin.py' cannot be loaded as Python module.

Any help appreciated, thank you
