Page Was Not Found Error on Registration

Hi There,

After testing new user registrations we get this error page. the only way to get round it is to hit return to get the next page. 

Can someone help? I have contacted my host and they confirm it is a dolphin issue. 

Could do with this resolving asap 

Thanks

Mark

Test on demo site and see if same issue there - if not, then it is something with your site - not a dolphin issue. Use the default uni or alt templates and see if problem persists. If not, then it is an issue with your template. You can try turning off all caches also and see if that helps. Also - how did you upload your files to server and install? Did you use an auto installer?
