Save, Preview no more working

Hi,

I need to modify one of existing forms, but I cannot save it and even cannot preview. Here is the message I have:

“Something went wrong while saving your form. Please try again.”

I created a new form. Was able to save the form with small number of elements ( about 15). After this the problem with saving appear again. What is interesting, sometimes it allow me to save one more modification, but most of times no.

I turn on debug, here is what I have in debug.log:

if ( ‘OPTIONS’ === $_SERVER[‘REQUEST_METHOD’] ) {
exit;
}
return $origin;
}
