Openprovider domain module bug with 5.11.2 & 5.11.1

In my production version when a client checks to see if a domain is available, they see confirmation if the domain is available:

A blank page usually indicates an error. Did you check your ../logs_blesta/ log directory (Full path set under Settings > System > General)? It may contain an important error. If you upgraded to 5.11.2, did you make sure to run /admin/upgrade? If you visit Settings > Company > Modules, the module does not have an Upgrade button next to it?
