After saving the product, the field "Product Category" become empty

[Grigorii]

Hello everyone.
The version of Virtuemart is 3.2.6 and Joomla 3.8.2
We created some categories, publishing them. But some created and published categories are not being showing in "Select Product Category". See the image:


When we open the product with this "invisible" category, the selected category is not showing in "Product Categories" field. See the image:


And if we select the category again and save the product, it disappears in the "Product Categories" field.
So, what the strange categories are they, and how to fix it?

Thank ahead to everybody for the any help.

Update Virtuemart to 3.2.8

Venci, thanks to try to help, BUT it still does not work after updating!

[Grigorii]

Yeah, we solved this trouble too!

1. We use Mozailla FireFox instead Chrome.
2. Use the NO CASH mode of browser, and it helps us.

We had this already and the reason is usally an htacess of the server which leads to problems with the caching.

Hi,

I'm having issues but only with a certain site on a server that runs many other sites that all work.

If this is htaccess, what can be done to fix it?

Is it an edit in the file?

Thanks,
James

search in that thread. I did the htaccess change and was fine for me after.
