When I clicked on the link in the email the site informed me that I was registered and verified. I was able to then logout and log back in without issue. The only thing that I noticed was that I did not get a registration email and had to click the verify button to get the message. I have attached some screen shots for reference.
How strange! The database obviously has my details recorded, but the site will not let me enter. The reason I know the details are recorded is that I clicked on the 'forgot password details' and put in my email address and received the correct details via email.
Would it help to re-upload the files pertinent to the login operation? Just a suggestion.
