We use a ticket system (GLPI) that uses the htmLawed library to clean HTML code from malicious content. The script in question is not handling the <font> tag properly.
Using <font> HTML directive is deprecated since a long time ago now.
Gravity Forms should be updated to replace this <font> tag by something else.
If you click on the radio box âModification de choix de coursâ, a table appears at the bottom of the page. When this form is submitted by email notification, it has deprecated âfontâ tag for that table.
