I downloaded the new PHP version 1.6.3a installer and extracted it to my c:\ root directory. It loaded fine but when I tried to access phpMyAdmin, it gave me the error...
"phpMyAdmin Error: Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly."
I did a quick search on the internet to see how much this problem was coming up and found the same error being generated on Windows platforms around the world. I followed the path... c:\xampp\apache\log\error.txt (the log folder) and found this error generated...
[Mon Aug 27 07:45:52 2007] [error] [client 127.0.0.1] PHP Warning: Unknown: open(C:\\DOCUME~1\\MyFolder\\LOCALS~1\\Temp\\php\\session\\sess_mph1aapojmqiaed5k0all04gp7, O_RDWR) failed: No such file or directory (2) in Unknown on line 0, referer: http://localhost/xampp/navi.php
I looked in the Temp folder and sure enough, no sessions directory. I added the nested folders ../php/session/ and phpMyAdmin came right up!
I hope this will save a lot of you a sleepless night trying to figure out why the adminstrator won't run.
Good luck...
