I recently made a change to my site and now some paying members can not login. Their UID and password are good because I can get into the system using them, they just can't on their PC's. I have had them delete temp. internet files, cookies, change cookie setting to look for new pages each, etc. but nothing seems to work for some of them. The code is written in php with a mysql database. The user tries to login but the page seems to refresh. They don't get any kind of invalid password message which is what would happen if they entered it incorrectly, it just seems to refresh the login page. Any ideas? Thanks!
We definitely need more info to be able to help. What kind of changes did you make? How is security implemented (session tracking, HTTP authentication, etc.?).
We seem to be working it out. Some members had the problem. Most did not. Some more stubbornly than others as I was able to fix a few. One member actually cancelled his subscription with paypal, started a new account using a credit card payment, then had access. Probably a little drastic but he was getting frustrated. The cookie programming was not something I was familiar with so I didn't want to mess with it.
