I recently changed the signup page for a site. It’s working for some, but for others it’s failing.
For whatever reason, the server is sometimes getting confused and running the old query.
Hosting support stated they don’t have any serverside PHP cacheing. OSCommerce cache is turned off. phpBB is the forum software, but only the forum database is involved here. What else to check?
ANSWER:
Check whether or not there’s a second sign-up form hidden elsewhere on the site.
Nothing to see here! Move along!
Try making it reload with something like a header()
Thats un-tested but mite give you somewhere to start.
