Overview

If you are using Kayako Classic and are unable to submit a case using the Helpdesk, you may encounter an error message stating 'Warningescapeshellcmd() has been disabled for security reasons'. This issue arises when the escapeshellcmd function, used for shell access, is disabled for security reasons. This function is called when the SMTP script runs.

Solution

To resolve this issue, you can follow one of these options:

1. If you host the Kayako site yourself, remove the 'escapeshellcmd' string from the disable_functions at the 'php.ini' file.
2. If you don't have access to the 'php.ini' file, ask your hosting provider to remove the 'escapeshellcmd' string.
3. Change your hosting provider to one which allows the running of the 'escapeshellcmd' function.

Additionally, disabling strict mode is a mandatory system requirement for Kayako Classic. You can follow the instructions in the article 'Disabling MySQL Strict Mode on the Server' to do so. Please note that providing additional assistance on this matter falls beyond the boundaries of the support services, as it pertains to the server and not directly to the application.
