Okay, I was able to verify that the script *does* execute :
Introduced an error in the script - script sticks. There's an obvious execution difference.
Remove the error, script seems to work. SO, we now know it executes the code, but the code does nothing.
Also, it generates an error in the general error log file, to verify that the introduced error was registered, and that the code was being executed otherwise:
[Tue Sep 06 22:22:59 2011] [error] [client 99.9.155.41] PHP Parse error: syntax error, unexpected T_STRING in /home/suaymac/public_html/includes/cron/iei_cron.php on line 24, referer:
http://suaymac.com/suayadmincp/cronadmin.php?do=modify
Okay, so now what?
The script runs, but does nothing (or rather, not the intended behavior) - not quite sure what other places to look into.
