Error registering products

[gabriellybit]

Hello,

I have a problem when registering my products in prestashop, every 5 registrations 3 give problem.

When I register the products and click on Save and Stay it leaves and returns to the page where it lists the products and does not save, nor does it display any error messages, I also checked the log and also nothing appears, it simply returns the page without to save.

What could be happening?

Thanks in advance.

Max_input_time and max_execution_time on server should be 300, you have only 30.
