It seems you are attempting to use the webDAV for connectivity to the program. Our shared servers do not support webDAV functionality, so if you are trying to use that with your OwnCloud application, it will get an error.
Scott, I want to use it too, why do you list it in softaculous if its not going to work??
Thanks for the comment! Apologies for the confusion. The issue has been brought to our systems team about removing the option since you can't use it. Sorry again for not being able to use product at this time.
