I found Joomla 4.2 + virtuemart4.4 Custom Fields don't open
Dear superha,
I'm quite sure you should make your question more specific.
Do they not open in the administration?
Are they not visible on the product?
Have you tried a different browser?
Do you have a picture of what the page looks like after "not opening"?
Does it show any kind of error?
Try to elaborate more on your request.
