Dear @suabahasa
I don’t use any cache plugin at the moment. I have possible cache problems only with Yabe Webfont.
I’ve uploaded 3 fonts. One of them shows on the frontend as the correct font but the name of the font in the backend keeps being the one of a font I deleted weeks ago, now I just know the trick.
The second font looks as in use in the backend, and can be selected and assigned to blocks, but then appears as a different font in the front end.
In a word nothing is working fine, sorry.
