Contact Form throwing error

I have GMail SMTP installed. On the contact form here-https://dbkpainting.com/request-an-estimate/, when I submit info, it throws an "Error 500", but the info is recorded in the feedback section of the site, but the emails are not set to the email specified in the form.
It was working about a month ago, and nothing has changed. I realize this may be out of the WPMU realm, but I hope you can help. Thanks

    Hello Chris,

    I hope you are well today.

    Generally speaking, 500 Internal Server errors are almost always related to a conflict between plugins or with your theme. Sometimes they are related to sever configuration issues.

    There's a couple troubleshooting steps I'd like you to try to see if we can narrow down the cause of this problem.

    First, could you please run a plugin conflict test as outlined in the following article? This will eliminate the possibility of a conflict with another plugin. https://premium.wpmudev.org/manuals/using-wpmu-dev/getting-support/

    If that does not lead to a solution, could you please enable WP_DEBUG and provide us with the output of your debug.log file?

    To enable WP_DEBUG, change the following line in your wp-config.php file:

    define('WP_DEBUG', false);

    To this:

    // Enable WP_DEBUG mode
    define( 'WP_DEBUG', true );
    
    // Enable Debug logging to the /wp-content/debug.log file
    define( 'WP_DEBUG_LOG', true );
    
    // Disable display of errors and warnings
    define( 'WP_DEBUG_DISPLAY', false );
    @ini_set( 'display_errors', 0 );

    After you've visited the pages that are causing you problems, please go to wp-content/ on your server via FTP and download the debug.log file to your local computer. Then, open that file with a text editor like notepad (Windows), GEdit (Linux), or TextEdit (Mac). You can then save the file as a .txt file and upload it here as an attachment to your post.

    I look forward to seeing the results of your tests.

    Best regards,

    James Morris
