Hi there,
I have upgraded my site to J4 and built up the template with Helix Ultimate 2 Framework. Now the standard contact form is throwing an error in the console when submitting the form
Uncaught SyntaxError: JSON.parse: unexpected character at line 2 column 1 of the JSON data
The e-mail is being sent but the progress circle is spinning without a success message. I had same problem before regarding this topic:

The solution was to update to the latest SPPB version. But now I have the latest version running and I already overinstalled without any success. So what to do now?
Here is the page where the problem occurs:
