That still didn't work, Cindy. Here is a screenshot to show you the Inspect Code. You can see it has the changes you requested (wrapping the text in the custom_control custom-checkbox).......but I cannot get the checkbox to show up unless I somehow change the input class of the zen_draw_checkbox_field () so that it doesn't say "custom-control-input".

That image should show the code and the still-hidden checkbox field.

To summarize.........This doesn't work:

Code:
<div class="custom-control custom-checkbox"><input type="checkbox" name="permLogin" value="1" checked="checked" id="permLogin" class="custom-control-input"><label class="checkboxLabel" for="permLogin" title="Tick this box to be automatically logged in on your next visit. Note: This will place create a cookie in your current browser that can only be read by this website.">Remember me?</label></div>
But this will work:

Code:
<div class="custom-control custom-checkbox"><input type="checkbox" name="permLogin" value="1" checked="checked" id="permLogin" class="LiterallyAnythingElse"><label class="checkboxLabel" for="permLogin" title="Tick this box to be automatically logged in on your next visit. Note: This will place create a cookie in your current browser that can only be read by this website.">Remember me?</label></div>
Is there anyway to change that input class when calling zen_draw_checkbox_field()?
