andThis program makes use of the Zend Scripting Language Engine:
Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies
with the ionCube PHP Loader v3.1.31, Copyright (c) 2002-2007, by ionCube Ltd.
The next suggestion would be to try increasing the PHP max execution time setting on your server.
I found out the default execution time is 30 seconds... does WHMCS needs more than that?
No, WHMCS doesn't, but if your DirectAdmin server is slow to setup accounts then it may need longer.
