ES noted that recent changes she'd made weren't appearing on the production site at francotoile.uvic.ca.
I had a connection in the exist admin client that used pear.hcmc.uvic.ca as the domain. I thought that would be dead, but when the connection succeeded, I assumed that domain name was forwarding to the current instance. Wrong. Obviously there is another instance somewhere on "pear" that is still running.
Created a new connection in the admin client using tomcat-devel.hcmc.uvic.ca as the domain and that worked. Also, the webapp in the new instance is francotoile and not francotoile21 as it was in the old instance.
In poking through the files, also noticed a connection string using lettuce.uvic.ca, so changed that to hcmc.uvic.ca and it seems to be working.
Updated the lastpass records.
