I'm not seeing this in my tests with the latest Virtuemart 3.8.8 and JCE Pro 2.9.14 - https://www.joomlacontenteditor.net/downloads/editor/pro/latest

My test is rather simplistic, with a stock virtuemart install and one "editor" custom field, tested while creating a new product.

Please send me a login - https://www.joomlacontenteditor.net/contact/site-login

The issue is caused by some javascript in Virtuemart, which attempts to create a new editor instance, before all javascript (including JCE javascript) has loaded on the page, ie:

<script type="text/javascript">// Creates a new editor instance
    tinymce.execCommand("mceAddControl",true,"field-15-customfield_value")
</script>

This script is in administrator/components/com_virtuemart/models/customfields.php on line 788 The reason this happens with JCE Pro 2.9.12+ and not JCE Pro 2.9.11, is that the way the javascript is loaded in 2.9.12+ was changed for Joomla 4 compatability. Nevertheless, Virtuemart should not try an execute a javascript function until it is sure that javascript function has actually loaded! Until Virtuemart fixes this (you might want to inform them of the issue), you will need to use JCE Pro 2.9.11 Not sure why this worked in my tests though...

[quotePost id="111086"]Hi
I am also having this issue.
I have joomla 3.10.9, virtuemart 4.0.2 and had JCE 2.9.22
Have brought the JCE back to 2.9.11 and is still an issue.
Any ideas on how I can fix it.
Thanks
Margaret

This is not an issue I can solve. You will need to speak to the Virtuemart developers about this.
