Hello, me too I have the problem to change cufon font on my site (inFocus wordpress).
I have already read all new inFocus documentation and forum workouts - nothing helped.
I generated a new Cufon-font through Cufon-font-generator, uploaded it to /inFocus/lib/scripts/fonts (checked the permissions - ok).
Then, I tried to change the font by two ways - neither worked.
/just to note/** I did all the theme customization by changing the /style/....css file - everything worked but for cufon.//
1 - I replaced in /style/.....css all 'font-family:colaboratelight;' with 'font-family:specialk;' (the same as the font generated by cufon - specialk.js) - instead of applying new font - it changed to simple serif (not even cufon).
2 - I changed all cufon fonts for the new one through the Skin generator in my dashboard (by going to 'Manage themes' > 'Edit') - the result was the same - simple serif! AND, moreover - it screwed up the whole style! my custom header, footer, meta and content fonts changed to default (though, I didn't touch these in the Skin generator).
-->In order to have all my settings and customization back, I had to completely upload the backup of my /style/....css file and image folder and rename it! Neither reuploading it with the same name, nor customizing the broken header/footer images and font styles in the Skin Generator - worked. All folders and files permissions were also okay (I always check it in the first place).
It seems like the theme understands and applies only the default Cufon font used in this or that style. I tried to switch to another theme with another cufon-font used - it was the same((
I hope I described my problem clearly enough :)
Please, help! and I don't want to do this through the Skin generator - it screws up all my long customization work and I have no patience left to re-customize it there anew... Thanks!
