Hi,

After following the instructions from email after procuring iRedAdmin-Pro license to upgrade my iRedAdmin, I can't access the panel with "Internal Server Error".

From the /var/log/messages contains the following :

Sep  6 11:01:36 example iredadmin:  File "/opt/www/iRedAdmin-Pro-LDAP-4.5/iredadmin.py", line 8, in <module>

Sep  6 11:01:36 example iredadmin: [x.x.x.x] GET /iredadmin 500 104 "-"

Hoping for guidance for this matter. Thank you.
