Modal issue , Login button is not working!

Hi i have installed the module, and set to Modal popup and enabled CSLogin "Load JQuery: YES", the login popup (Modal) is not working!!
Im using Helix Ultimate Template by joomshaper, Joomla! 3.10.2
Can you please tell me what is the issue?

Thanks for the reply I just send it to you privately from the contact us page. Did you receive it?
But we can continue to talk here.

I'm having a similar issue. I updated a website from 3.9.28 to 3.10.3 yesterday. The 3.9.28 website has only one script that contains #login-modal, but the 3.10.3 website has 2 scripts that contain #login-modal. One references JCaption and the second is the SourceCoast login script.

Here's what the JCaption script looks like in the 3.9.28 website:

<script>
jQuery(window).on('load',  function() {
                new JCaption('img.caption');
            });
if (typeof jfbcJQuery == "undefined") jfbcJQuery = jQuery;
    </script>

And here's what it looks like in the 3.10.3 site:

<script>
    jQuery(window).on('load', function() {
        new JCaption('img.caption');
    });
    jQuery(document).ready(function($) {
        $('#login-modal').on('show.bs.modal', function() {
            $('body').addClass('modal-open');
            $('.modalTooltip').each(function() {
                ;
                var attr = $(this).attr('data-placement');
                if (attr === undefined || attr === false)
                    $(this).attr('data-placement', 'auto-dir top-left')
            });
            $('.modalTooltip').tooltip({
                'html': true,
                'container': '#login-modal'
            });
        }).on('shown.bs.modal', function() {
            var modalHeight = $('div.modal:visible').outerHeight(true),
                modalHeaderHeight = $('div.modal-header:visible').outerHeight(true),
                modalBodyHeightOuter = $('div.modal-body:visible').outerHeight(true),
                modalBodyHeight = $('div.modal-body:visible').height(),
                modalFooterHeight = $('div.modal-footer:visible').outerHeight(true),
                padding = document.getElementById('login-modal').offsetTop,
                maxModalHeight = ($(window).height() - (padding * 2)),
                modalBodyPadding = (modalBodyHeightOuter - modalBodyHeight),
                maxModalBodyHeight = maxModalHeight - (modalHeaderHeight + modalFooterHeight + modalBodyPadding);
            if (modalHeight > maxModalHeight) {
                ;
                $('.modal-body').css({
                    'max-height': maxModalBodyHeight,
                    'overflow-y': 'auto'
                });
            }
        }).on('hide.bs.modal', function() {
            $('body').removeClass('modal-open');
            $('.modal-body').css({
                'max-height': 'initial',
                'overflow-y': 'initial'
            });
            $('.modalTooltip').tooltip('destroy');
        });
    });
    </script>

Both sites are accessible if you would like to view the source.
3.10.3 site: nobot.org/stage/index.php
3.9.28 site: nobot.org/members/index.php

I also see the different jq-bootstrap versions. If anyone can provide guidance on how to get the modal login in the 3.10.3 website to work, I would appreciate it. 

Thank you for the information. I was able to work around the issue by installing the SCLogin v8 plugin and adding a script to the header that loads the older bootstrap version 1.8.3.js. But, I will try your fix as I really want to use v9.

I deleted the mod_sclogin override folder and tested the v9 login module with both the default and sourcecoast templates, but neither would work as a modal box. I will use the v8 version for now until I have more time to look into what's causing the issue. Thanks again.

I've reinstalled v9 and deleted the override folder. Site is here: nobot.org/stage/index.php
The login link is in the top left corner above the round logo. It will be moved to top right when I can get it to work. Let me know if you have any questions and thank you for your help!
