Hi folks,

Just moved a Discourse instance to a new server using the builtin backup functionality. Everything went smoothly, except some of the old CSS overrides don’t seem to be working anymore, and there’s a lot of this in the logs:

`Error: Template was precompiled with an older version of Handlebars than the current runtime. Please update your precompiler to a newer version (>= 4.0.0) or downgrade your runtime to an older version (>= 2.0.0-beta.1).`  
` at Object.r [as checkRevision] (http://selectbutton.net/assets/vendor-b446ddf94c0fbadd8f0c95717a0ead0e.js:1:10979)`  
` at Object.i [as template] (http://selectbutton.net/assets/vendor-b446ddf94c0fbadd8f0c95717a0ead0e.js:1:12411)`  
` at r.e.template (http://selectbutton.net/assets/vendor-b446ddf94c0fbadd8f0c95717a0ead0e.js:1:2821)`

Tried rebuilding a couple times and toggling the overrides on and off but that doesn’t seem to be working. Any advice?
