Sitejet: Submitting from a contact form generates an error

Symptoms

When submitting the contents of a contact form created by Sitejet, the submission fails and you can find the PHP warnings in the following file:

/home/$user/logs/$domain_tld.php.error.log

The warnings will resemble the following:

[01-Jan-20XX 00:00:00 UTC] PHP Warning: Undefined array key "form_196935989" in /home/user/public_html/api.php on line 240
[01-Jan-20XX 00:00:00 UTC] PHP Warning: foreach() argument must be of type array|object, null given in /home/user/public_html/api.php on line 240

Description

Once the form is submitted to the server, the local PHP settings take over and certain configurations can cause warnings to appear. Ensuring that the PHP settings are properly configured, the PHP is running the appropriate version, and that the Sitejet plugin is the latest available version should resolve these warnings.

Workaround

• Ensure that the site is using a version of PHP 7.1, 8.1 or higher:
