I have a logon screen that starts a session for several other pages and it
has been working great,
over the weekend something happened. I checked the site from home and
after login the main
page would not load, just a white screen and view source showed absolutely
nothing. Now I'm in the
office and looking at the source code and I don't see anything wrong,
nothing changed. I can load the
pages by skipping the logon and typing in the complete url manually and
they all load just fine, soon
as I try to use the logon screen the first main page after it will not
load, if I enter the full url to another
protected page it will load, then I can use the links for the main page
and it too will now load. Just after
the logon, the main page will not load. I have tried this with both my own
login and a users login and
it is happening to all.
Any idea what could be causing this? I've gotta get this fixed ASAP,
perminently, this is a business web
site. The code for the login screen and the main page are pasted below.
