Login problems

[LauraM]

Hi, All,

Over the last two or three days, I've had numerous members contact and tell me that their login info is not being remembered.

These are all old, established members that are very familiar with the forum and knows how their accounts work. They are either not able to log in, being asked to reset their password, or when trying to post a reply or thread, they get a message saying that the thread doesn't exist, or that they don't have permission to post. When they go back and try again, it generally works correctly.

Also, many have said that, just out of the blue, their settings for viewing posts in forums was inexplicably reset to view only threads from the last day.

Both me and the other admin on my board have had problems with being logged out completely and having to log in again (as well as check the "remember me" box) and trying to post and getting the message that the thread doesn't exist.

Is there something I can check to see what is going on? A setting somewhere?

I'm not terribly experienced with this sort of things, so explicit instructions would be good. My tech is very busy at the moment; he's moving his store to a new building and having to also find (and then move) his servers (which my website is on!) to a new colocation facility because the current one is closing, so I really don't want to bother him right now if I can possibly figure out this problem and fix it on my own.
