Hello Frank18,
I am having the same symptoms and problems. Could you give me a clue which jscript was interfering with OPC and how you fixed it.

Thanks, Frank

In the file includes/templates/YOUR_TEMPLATE/common/html_header.php I commented these 2 lines:

<script type="text/javascript">window.jQuery || document.write(unescape('%3Cscript type="text/javascript" src="//code.jquery.com/jquery-1.12.0.min.js"%3E%3C/script%3E'));</script> 
<script type="text/javascript">window.jQuery || document.write(unescape('%3Cscript type="text/javascript" src="<?php echo $template->get_template_dir('.js',DIR_WS_TEMPLATE, $current_page_base,'jscript'); ?>/jquery.min.js"%3E%3C/script%3E'));</script>

Worth a try on your site. But only as a temporary test.

lat9 has been trying to reproduce the issue on one of her dev sites, so far to no avail. So my suggestion may not work for you.
