Landing page has an error in JQuery

Dear people,

We are using your plugin on a wordpress website. One of possibilities we see to insert people on the list for our newsletter is using Landing Form. I made a simple test page with where I only insert a shortcode of the Simple Form I created in:

Smart Marketing > Capture Contacts > Simple Forms

The code in HTML Code text field is the following:

[e_name]
<p>
  <label for="egoi_name">Name: </label>
  <input type="text" name="egoi_name" id="egoi_name" />
</p>
[/e_name]
[e_email]
<p>
  <label for="egoi_email">Email: </label>
  <input type="email" name="egoi_email" id="egoi_email" />
</p>
[/e_email]
[e_mobile]
<p>
  <label for="egoi_mobile">Mobile: </label>
  <select name="egoi_country_code" id="egoi_country_code" data-selected="1"></select><input type="text" name="egoi_mobile" id="egoi_mobile" />
</p>
[/e_mobile]
[e_submit]
<p>
  <button type="submit" id="egoi_submit_button">Submit Simple Form</button>
</p>
[/e_submit]

Also I have activated Double Opt-In option which probably doesn’ affect the error.

The error that I get in the browser is

–jquery.min.js?ver=2021111811:4 Uncaught TypeError: b.replace is not a function

The HTMLFormElement.<anonymous> ((index):709:48) is within submit function in the line with the following code:

button_obj.text(".").prop("disabled",true).css(button_style);

I am sorry I cannot send you the link. I could send it only if it were not public. Is there a way?

How can I resolve the situation?

Have a nice day,

Igor
