1) PHP5/fcgi?
I have all my site using php 5 some with /or with out fastCGI
I'd suggest switching if you can as I forgot what was not supported with php4... someone else may remember.. but I'd switch if I was you...
2) what's this config file message about and
with permission for config.php, it will show x for anything were it can be written... you would want to set it at 644... only set at 777 when you are needing to edit the file then change it back... but that would not cause your problem... it's just a security issue
3) how's the weather over their in the palouse? (Kind a grey and typical here in Seattle.)
Weather is nice.. day is crapy... my server is wigging out on me..
did they get those logs... that would point out at least an error... also you could set $config['debug'] = true; ~line 31 in the config.php (one of the time you'd edit it) that may throw some light...
I'm afraid thou I'm going to be stuck doing my server for the next few hours -to- day.. I'll try to get back but may-be some one will pop in and lend a hand before...
