Today I spent the day trying to solve a problem with user registration. I did not notice this problem until I put the site live because it was working on local server.
Simply I wanted to register a new user from a login module and the result was this message:
Page Could Not Be Loaded
We're very sorry, but the page could not be loaded properly. This should be fixed very soon, and we apologize for any inconvenience.
Debug Info:
Status: 500
Response: Service Unavailable
XID: 316945260
First I checked the "Allow User Registration" which was set to yes.
Then I tried both the K2 user module and joomla login module but the result was the same.
When turning on the debugging mode the problem disappeared and the registration page was shown.
I went back to an old backup with joomla 2.5.4 (from 2.5.9) + K2 v2.5.7 but the result was the same.
Finally after some other tests I disabled acymailing, K2 store and K2 and now the joomla registration was working. I then isolated the problem to K2 and it was enough to turn on the System-K2 plugin to trigger the problem and all other K2 modules disabled.
Maybe I have missed something basic, my only guess at the moment is that certain joomla modules must be disabled in order to use K2 user and vice versa. I did some trials of this without success.
I hope there is a simple solution for this.
