That can be the result of a failed or slow SMTP connection (when sending notification emails on reply). A failed SMTP connection will normally show in the log:
Admin CP -> Tools -> Server Error Log
If the log contains mail errors then you need to check your SMTP info:
Admin CP -> Home -> Options -> Email Options
You can also try adding this line to your library/config.php file to disable mail functions:
Code:
$config['enableMail'] = 0;
Does that fix the problem? If so then we know it's a mail problem.
Ill go through them one at a time. I was using my hotmail as the site email but changed it to an on server email. If i still get it ill change the settings from default and put in the info manually. If i still get it ill change the config. If im still getting it ill report back.
