Still got the issue
Thanks. I've had a look at the link you have provided.
Seems I've got a problem with updating fields using the users_Update.php file in my Admin Back End section.
I thought it was just my new .php update page, which I had created, that wasn't working but it would seem that the default page isn't working as well. Have tried deleting the users_Update.php file and replacing it with a brand new unedited version from the original downloaded software but it still isn't working.
Front End field updating works great via users_Profile.php and updates the database just fine but when I login to the admin area I can see the details and fields, via users_Update.php, but there is no change to the database once I have pressed the "Update" button.
Anyone have any ideas?
