 * Just installed the WordPress 5.8 with HTML Forms 1.3.22. Found two PHP Warnings
   in the error_log file after I tried to send a test message from a contact form
   created with HTML Forms plugin:
 * > Undefined array key “required_fields” in …/wp-content/plugins/html-forms/views/
   > tab-fields.php on line 21
   >  Undefined array key “email_fields” in …/wp-content/
   > plugins/html-forms/views/tab-fields.php on line 22
 * HTML Forms 1.3.22
    Wordpress 5.8

 * What PHP version are you using?
    If you are not sure you can ask your webhost,
   or install a “phpinfo” plugin to see the version number.
 * Thanks for letting me know.

 * PHP 8.0 (ea-php80).
 * Checked today again. The warning can be reproduced when a new form is added (
   probably after saving) with the default fields.
 * I don’t know, but maybe this warning is produced because of my HTML Forms custom
   hooks, I will check this later.

 * Would be great if you can test without your custom hooks yes. And otherwise maybe
   see if it’s related to PHP8, switching to PHP 7.4 (as a test). If it is not your
   custom hooks, please do let us know what you find!!

 * Ok, so far the problem has not been repeated, I guess the plugin was not the 
   cause, so we can consider it solved. Thank you for the support!
