Note: Don't change the DocumentRoot to the blog, as this will destroy the design of the wiki. The last rewrite rule will decide the default site!
===Changing the blog url===
It seems likely that some Reddit bots are automatically blogging postings with the word blog in their URL. So I decided to move my blog from /blog to /article. (Note that it is singular. I considered 'paper', which is shorter but not quite right. Likewise 'study', etc. Also 'journal')
To do this you have to (see https://wordpress.org/support/article/moving-wordpress/):
#Create the new directory
#Make the change in Wordpress through wp-admin (you have to do this first!)
#Move the directory
#Fix the aliases in apache
#Fix the permalinks
#Fix the images etc.
#Fix the permissions
#Create a new icon image
