Can't change permissions on a page

[lm]

I am getting the error:

"There was an error submitting the page restrictions. Please try again later."

I can't add a new team member to our wiki to view documentation.. Help?!

Hi! 

Have you ask from admin (who has admin right in the space or for all instance) about this restriction ?

I hope this person can unrestrict. 

Or you met with errors. let's open browser console log where you can see some errors related that

Cheers,
