Your SEF Settings was causing this error for now I have disabled below settings in admin panel > global configurations > Seo Settings.
- Code: Select all
Search Engine Friendly URLs - Disabled.
Use URL rewriting - Disabled.
I have noticed your server is Windows IIS so you need to do following.
Rename "web.config.txt" to "web.config" then re-enable above settings under Seo Settings.
If above doesn't work then make sure your server supports rewriting urls by checking to make sure "IIS rewite module" is installed and enabled. For more information on enabling this module please see following link.
