Blank page new product or edit product

[gettoweb]

I installed prestashop 1.7.5.0
Php version: 7.1.25

Memory limit: 512

I entered more then 10 000 products.

When I want to open or edit a predict I get a blank page. (HTTP 500 error)
Even when I set the memory limit tot -1 unlimited it doesn't work.

Error log:

Backend fatal error: PHP Fatal error:  Allowed memory size of 536870912 bytes exhausted (tried to allocate 184320 bytes) in Unknown on line 0\n

10, 000 products is big, you should split into smaller parts. example 1,000 products / 1 time

Thanks tdsoft for your reply.

The import of 10 000 products worked. I did it via module import.

But the problem is = when I want to edit a single product or add a new single via the BO I get a white page.
