Hi @Ptran,

I can’t replicate that problem – are there possibly any modifications to the code? Are there any warnings above that message in the log? Do you have your PHP configuration set to send errors/warnings to the browser, or just the log file?

hi Alec,
I haven’t modified anything else but the config.inc.php file to turn on the debugs. There are PHP Notice above the errors.

I don’t have PHP configration set to send errors/warning. I got this errors from the apache log.


Never mind, I got this figured out.
