Thanks for that advice. I did do a complete uninstall and then manually reinstalled using the download from the Zen Cart website.
However, after renaming the install files folder and adjusting the admin version of configure.php and renaming the admin folder, I still have the same situation of being able to access my store as a customer but not being able to get to my admin login to tailor the store. My browser times out and then gives up saying that it can't display the file.
I don't believe it's a file permission issue because I put a copy of phpinfo.php into the renamed admin folder and I can execute that just fine. I also tried renaming the .htaccess file but that didn;t solve the problem either.
I haven't added any debugging printouts to this latest version yet, but when I did that with the earlier installation that was having the same problem, I found that it was hanging up right at the tail end of the *required *application_top.php script and wan't returning to the login.php script from the *require *statement.
:ohmy:
