Error 503 on page 503 of the backoffice goods list after limiting to 1000 products/page

[Mastery Gamer]

Hello, I've increased the number of goods that can be displayed in the back office to 1000 from the previous setting of 500. I only had to wait a little while for it to take effect. Since yesterday, it has been giving me 503 errors. I believe this is because it is still trying to load the 1000 products, which may be too heavy this time.

Is it possible to manually alter the quantity of products displayed from a file or a database?
