It’s not a problem with generators,
The current problem is that dots are not allowed in the page name, and it's causing the error,
You can wait until the problem is fixed or change the URL to something that doesn't contain dots.
Thank you for your help. i have also tried this option and it also refuses to accept. I’m wondering if I should wait for the problems to be resolved or I don’t know how to do it. What do you suggest?
Try use this one https://i.xat.wiki/sc/ select "FACEBOOK" and fill the page name only and see if it works on your xat edit.
Anyway i generated one to you, only copy and paste on edit.
