[SOLVED] Typeface changes to serif

The demo site I'm working changes the fonts to serif on another computers.
Any reason why and how do I make it keep the standard Open Sans Serif?

It changes when viewed in Safari to Times Roman.....

Thanks!

Hi there,
which font did you selected?
I cant see any issue in Saffari on our demo.

Please make sure that no external ressources ( fonts) are blocked by your Browser or firewall or antivirus tool.

Yeah it was strange. I had Open Sans and Montaga but I solved it by adding: !important; to the custom.css and to the bootstrap.css where the font was listed. Now Safari and Chrome show the font correctly

Problem solved.
