After being a bit lax, I`ve got round to upgrading my forum from 1.3.5 to 1.4.7 The install appeared to go fine, but today I had a message saying a new user couldn`t register. I tried it myself & it failed with the following errors 1.Some fields contained unexpected data. Please try again or contact the administrator. 2.Please enter a name that is at least 3 characters long. 3.Please enter a valid email. 4.Please select a valid time zone. 5.Please enter a valid location. 6.Please enter a valid password. 7.Please enter a value for all required fields. After a search on here I found another user had the same problem so I did what fixed his isssue. I reuploaded the files & tried to run the forum/install. The installer then said I was already running 1.4.7 but to delete the internal data/install lock.php file to reinstall I did so & tried to run the script again but it now seems to think I`m doing a FULL install as it wants to delete my database. HELP!
