I was using Oxygen for quite some time without issue and recently when the brute force attacks began happening on WordPress sites my Oxygen theme started acting funny.
If you browse to http://www.onthewaytosomewhere.com you will see that the title, top menu and a few other areas display Times New Roman instead of Abel (and other fonts).
If I simply login to my dashboard (wp-admin), it fixes the problem. The fonts will display for maybe 2-3 days and then revert back to Times New Roman.
I know when the attacks began some time ago, my host did change their server configurations and I did install Better WP Security. I have not changed anything from the standard configuration of this theme.
If anyone has any thoughts or suggestions to try I would really appreciate it!
