WP-cufon is working perfectly in Chrome and Safari, but Firefox an Explorer will not enable cufon in the welcome page, which is the blog roll.
I think I tried about all setting combinations (Additional features and cript positions)in the Cufon Settings page.
When I compare the generated code online, I can't find any difference in the way the cufon code is integrated in the post page compared to any other (cufon enabled) page.
Any suggestions?
