Custom field Time - not working

[lavoro83]

HI,

I use Joomla! 3.6.0   and VirtueMart 3.0.18 and have created Custom Filed (Virtuemart>Products>Custom Fieleds). It's Custom Field Type: Time.

I have saved it and selected it in the product tab Custom Fields, but nothing happens on the frontend. No option is saved???
When I have created the custom field date than a calendar has shown in the frontend and backend.

So I wonder how this field type works and how I can fix this, because I need for the customers to select arrival time.

I am sending screenshots as attachment.

Thanks

I use Joomla! 3.6.0

Before doing anything else, update your Joomla!!!
You must update to Joomla 3.6.4!!

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

I have updated Joomla and checked for new users, there aren't, but this didn't solve the problem.

The upgrade to Joomla! 3.6.5 (the only-one available in the backend)has created a problem with the module VirtueMart Products. When I click to enter an existing one or try to create a new one, all options are gone??? You get only a blank page with drop down menu for selecting position.   

What is the highest version of Joomla that VirtueMart 3.0.18 is compatible with?

all my sites are VM3.0.18/J3.6.5 .. I have never seen this problem

the error causing this must be logged some where

Can you help me to find the log for the error? Where I should search ?

Also write me if you have ever used the Custom field Time, is it working for you and how?
