Reference Documentation Disappearance

[Gustafson, Nicholas]

Hi,
It seems like some time this morning (JST) the documentation for Grammar, 
Functions, and Datatypes was replaced with a single line: “update_here”.  
Example: https://phoenix.apache.org/language/functions.html
My guess is this was a mistake, but I’m not sure how or who this should be 
reported to.  Does anyone have an idea of how to get these pages restored?
Thanks,
Nicholas Gustafson
