Warnings about layout when trying to build site


#1

I set up a Hugo Server (with the Academic theme) a few months ago and everything worked fine. Then I updated a PDF file and tried to build again (Hugo server) but I received a lot of warning and the local site is just a blank page. The warnings are like the following:

Found no layout for "xxx", language "en", output format "xxx":.
