After I did small changes to a website (not touching the form at all), the form suddenly stopped working.
I tried on another website, not even changing anything on the entire page with the form, only other page (only text changes). The same thing happened.
My webserver has PHP 8.4 (hostinger), and no details in the form at all are changed. The page is set with .php extension (index.php). However, I notice that adding ?apicheck to URL no longer work at all.
I also tried to publish all files, but no difference.
I’m on Mac - Tahoe 26 (and iPhone iOS 26 also tested).
