Self service tool not working

Hi;

I cannot make an update on the product detail page with the help of the self-service tool. I saw that the self-service tool screen did not turn on.

I've done a lot of updates recently. But now it gives the result in your screenshot.

(Request a product detail page change

Updates cannot be made to this product detail page at this time.)

What can I use as a self service tool alternative?

Or how can I solve this problem?

I need your support..

Thank you from now.
