No custom Fields. Please use select list to add some new fields

Joomla 3.6.3 and VM 3.0.18

Strange thing happened. Im trying to update a few products and suddenly I cannot add an existing custom field to a product. I select my custom field from the drop down list and it doesnt display the multi variant box. Just shows No custom Fields. Please use select list to add some new fields.

If I open a product that already has existing custom field it works fine. If I choose a product that didnt have any custom fields and want to add custom field multi variant I cannot.
However if I want to add a string...it works fine, just doesnt work for multi variants for some reason now. ??
Any help with this please? Thank you.

EDIT
I think this just started after updating Joomla from 3.6.2 to 3.6.3 I cant confirm for certain though. Thats the only update Im seeing since I was last able to add multi variants.

First update Joomla to 3.6.4 - 3.6.3 has a big bug.
Then clear your browsers cache, close browser and open it newly, try now - helped me.

You are using Joomla 3.6.3 so you must also consider that your site may be compromised.  If not, then UPDATE JOOMLA NOW. All Joomla versions since J3.4.4 contain an open door for hackers to register themselves as admins and thus have permissions to cause damage.

Check if you have new Joomla users with administrator permissions - if so hackers have paid you a visit!

Thanks for the quick replies and info.

No new users. I updated last night to 3.6.4
Cleared cache and expired cache.
Closed browser and reopened and still cannot add multi variant to a product. If I create a child product first then go back it allows me too create a multi variant.
Strange.

Also I can add strings no problem, just multi variants are the issue now. Any other suggestions or files to look into? Thanks again for your time and help.

Can you test with this version? There have been several updates which may solve your problem, it is a pre-release version so try on a backup of ypur site.

Thank you for the link Jenkinhill. That did not work either. Any other suggestions?

Did you check your permissions of VirtueMart?
Furthermore check the vendorIds. You may enable multivendor to see the vendorids. You may got hacked, an hacker can hack you, add an account and remove it.

How would I be able to confirm if a hack took place or not? Is there a tool or utility that would check or a list of files to compare to?
Also where would I check vendorids as you mentioned in your reply? Thank you again for your help and patience.

That is a big topic of its own.

This patch works usually with a new user which takes admin rights. Or one of your admins is suddenly superadmin or a password of an superadmin got changed. And then, they can do anything. Defacer just make fun with you. Someone in the community had the case that any user was set to get the system emails. So you should first check your users. At least check the superadmins

Thank you Milbo. I have checked users and nothing out of ordinary appears. I am the only active user listed. The ite is still in testing mode and not live, so Im thinking we may be ok as far as hack goes. Ill ask host to see if any suspicious activity took place and see if they can confirm anything.

Is there a particular file that would affect the custom fields list from being displayed and used? Id like to check that file to see if any modifications where made which might have affected the functionality. We were supposed to go live but this throws a big monkey wrench into the works. Appreciate any advice or help with this.

Then it is quite certain, that nothing happened.
