Missing Weight field at Admin - Product Edit

Hello, community friends.

For no apparent reason, the Weight field disappeared from Admin, at the product edit/register page (Catálog > Products > Insert >Data). I'm really refer to the field where we insert the product weight, that used to be above the combo-box where we select the weight unit.
I've already lost a lot of time and I still couldn't figure out what happened with the missing weight field.
In a test server, I've have done a clean Opencart installation with my current theme and extension, and as expected, in this test server the Weight field is right there.
Does anyone have any idea about what is happening?

Thanks a lot!

Hey there,

Do you remember what were the last extensions that you installed?

You can disable all vQmod extensions and see if any of them is causing the problem. Go to the vqmod/xml directory on your server, create a new directory and call it disabled. Move all xml files to the vqmod/xml/disabled directory, except (!) for the vqmod_opencart.xml file. If you're using any kind of caching module, make sure to clear the cache from the OpenCart admin. Then reload the Catálog > Products > Insert >Data page and see if the problem is still there. If it isn't, one of your extensions is causing it.

Hi, gerganadimova.
Thanks for help. You were right. An specific extension ( Openstock ) was causing the issue.
I've already submited a support ticket and I hope Openstock staff can fix the problem ASAP.
