Thanks for reporting @achillis. The raw css is correct, but the minified version is not indeed.

there are several related files (6) that has some issue

Do you mean the rest of font types (woff2, woff, ttf, etc) links for the same glyphicons, or did you find broken links somewhere else in the minified version (or in any other file shipped with b2evolution)?

I apologize for the confusion, I meant six other links in the minified file.

Also, is there a reason why the core files for bootstrap is not updated to the most recent released version? (V3.3.7) or can this perhaps be updated in a future (next) release?
