Contact Form HTTP Error 500

Hi there so the contact form for my site I am building for a client is hosted by godaddy and is returning an HTTP Error 500. I contacted them and they ran a test script saying everything works from their end. Also, they said that it works fine with either PHP or SMTP and that the issue revolves around the contact form script. I'm not sure what the issue could be as I followed the https://docs.semicolonweb.com/docs/forms/form-setup/

Here is the code for the contact form and form.php:

<div class="form-widget">

										<div class="form-result"></div>

										<form class="mb-0" id="template-contactform" name="template-contactform" action="include/form.php" method="post">

											<div class="form-process">
												<div class="css3-spinner">
													<div class="css3-spinner-scaler"></div>
												</div>
											</div>

											<div class="row">
												<div class="col-12 form-group mb-4">
													<label for="template-contactform-name">Name <small>*</small></label>
													<input type="text" id="template-contactform-name" name="template-contactform-name" value="" class="form-control required">
												</div>

												<div class="col-12 form-group mb-4">
													<label for="template-contactform-email">Email<small>*</small></label>
													<input type="email" id="template-contactform-email" name="template-contactform-email" value="" class="required email form-control">
												</div>

												<div class="col-12 form-group mb-4">
													<label for="template-contactform-message">Message <small>*</small></label>
													<textarea class="required form-control" id="template-contactform-message" name="template-contactform-message" rows="4" cols="30"></textarea>
												</div>

												<div class="col-12 form-group mb-4 d-none">
													<input type="text" id="template-contactform-botcheck" name="template-contactform-botcheck" value="" class="form-control">
												</div>

												<div class="col-12 form-group mb-0">
													<button class="btn text-larger btn-dark bg-color px-4 py-2 rounded-pill" type="submit" id="template-contactform-submit" name="template-contactform-submit" value="submit"><i class="bi-envelope color-2 ms-1"></i> Send Message</button>
												</div>
											</div>

											<input type="hidden" name="prefix" value="template-contactform-">

										</form>
									</div>

// End of SMTP

So I've added the classes to the correct locations as mentioned above. This might a dumb question but where will I test to see the potential errors I get? For example, if I test on the live godaddy server host, where would I see the error message?

I tested on the live server using only PHP and no SMTP and got a success message but still haven't received anything in my Gmail email. I don't if this will help speed up the issue or not.
