PDFs not opening

[ghost]

PDF.js loads but the file doesn't.
I get these errors:

GET http://192.168.1.134:8090/static/reader/pdf/build/pdf.js 404 (Not Found)
viewer.html:1 Refused to execute script from 'http://192.168.1.134:8090/static/reader/pdf/build/pdf.js' because its MIME type ('text/plain') is not executable, and strict MIME type checking is enabled.

Hmm. I'll fix this in the next version of BookBrowser. It seems like the wrong mimetype is being sent.
