Adding product to the basket Product removed message [solved]

[denata12]

Hi Everyone,
I have VirtueMart 3.6.0 with Joomla 3.9.6.
When add product to the basket some time i receive this message "Product removed". Somtimes it happens, sometimes not.
The clients noticed the same error too.
Can you help?

I tried to stop - Pop up "Ad to cart"
Turn off - Using the VirtueMart jQuery
Turn on - Load Joomla jQuery Framework
I managed to add the product to the cart, but some other users not.

Can you help?
Thank in advance

Old versions, VM is now at 3.8.6 and Joomla is 3.9.23   The issue you see may not happen with the current versions.

Have you checked the browser console for JavaScript errors?

Thanks for the reply

I will try to update them tomorrow.

Here are the mistakes
Opera
Failed to load resource: the server responded with a status of 403 ()jquery.ui.autocomplete.html.js:1 Failed to load resource: the server

Firefox
The resource from " /components/com_virtuemart/assets/js/jquery.ui.autocomplete.html.js" was blocked due to MIME type ("text/html") mismatch (X-Content-Type-Options: nosniff).

About this "Product removed message", not for these java mistakes, right?
Can you give any guidance?
I will check tomorrow, when I have access
