I thought maybe the template had been updated. I checked and I'm using version 1.0 of the Incline template. So I tried to upload the latest copy of the Incline template, and got this error:
Extension Install: Another Template is already using the named folder: /var/www/vhosts/stlmm.org/httpdocs/templates/incline. Are you trying to install the same extension again?
