The front end registration form on my client's site takes the info and even acknowledges success - and the admin gets notified. But the info isn't getting into the db/ee back end anymore.
This registration form has been working OK for years, the rest of the site is OK as well.
The form uses User 3.4.5 which is no longer supported by Solspace.
The site was recently moved to a new server - en masse with the rest of my hosted accounts.
My server admin looked at this and here's what he got when he turned on error reporting. I have no idea how to use this information.
