I used WP Google Fonts for weeks for my titles & paragraphs when I've seen this morning that I could update the version and move to V3.1.
I thought it would better use with Wordpress 3.5.1.
On the contrary, all my titles (H1,H2 ...) are at the same size as paragraphs !
Do you what happened ? Should I paste a code in quick CSS ?
Thanks a lot !
