URGENT ! Unable to change product specifiactions in admin panel.

Hello.

My issue is the following :
I'm using opencart 2.0.3.1, everything is fine, but when it comes to editing products specificaitons in the admin panel it doesn't work for some of specifications. For example I created a new product called "Test2", with model name "Test" and price 0.00

Then I tried to change the model name to "Tested" and the price to be 5.00, but there was no result.
I'm experiencing this with each of the products.

Can you please advice me what should I do, because I was looking for this topic everywhere, but there is nothing about it ?

Hello, again.

Thank you for your quick response.
I checked the other topic, but since I am not so qualified I am not sure what to do.

Would you be able to explain in more details how to fix it ?

Best Regards.

Hello.

I solved the problem. I did new fresh install of opencart.

Regards.
