Similar to this question, however the answer seems to have not paid attention to the actual problem- TechNet Forum
I am attempting to change the URL of one of my site's child webs through "Site Settings -> Title, Description, and Logo" - the option for changing the URL is on this page. When setting the new URL, then clicking OK, I receive an error page
"The attempted operation is prohibited because it exceeds the list view threshold enforced by the administrator."
I know all about list view threshold. What does it have to do with changing my site's URL? Is there a list in the config database that stores the URLs- and maybe there are too many webs or something for it to perform this type of operation? Seems terrible.
