Insert Form In EngageBox

Hi,
thanks for the backup.
This is really a complex environment.
I think, I found the source of the problem and was able to improve the visforms code.

I've just release visforms 4.1.3 which contains the bugfix.

I can now load the "home" menu entry, without any further error.
I did not dig deeper into the structure of your website, so I do not know, whether everything works now as you expected.
But the visforms related "HMTLHelper visforms not found" error is fixed.

I noticed, that your regular expressions in the field validation cause a javascript error, because they are incorrect. Opening bracket is escape, so checks for the character (
Closing bracket is not escaped, so it is  interpreted as the closing bracket of a group, where the opening bracket is missing.
This causes a Uncaught SyntaxError: unmatched ) in regular expression
A correct regex would for example be
And there is a javascript error caused by components/com_sppagebuilder/assets/js/sppagebuilder.js
