I think that you are on to something, I put the date in, uploaded the page, it showed that the update had been made (the file appraiser_LogIn.php reflected the new modified time), however the changes did not show in the browser.
When I enter the page, it is
appraiser_LogIn.php
After I enter the log in information, the url is now
law_firm_LogIn.php?accesscheck=%2Fappraiser_Profile.php%3Faccesscheck%3D%2Fappraiser_LogIn.php%3F%26accesscheck%3D%252Fappraiser_Profile.php%253Faccesscheck%253D%25252Fappraiser_LogIn.php%25253F
It appears there is a redirect to law_firm_LogIn.php, which is the other log in page I have on the site.
When I do an incorrect log in on the law_firm_LogIn.php page, the url does not change....hope that helps.
What should I try next?
