I had the same last week trying to set up mine..it proved out that the problem was and still is just on preview mode during editing..when I published my site, in the "real"-live view was ok!

Ok @Simona Griskute and everyone else, for me problem solved! I just published my site and in live looks fine with my customisation. That means the issue occurs only in the preview mode during editing. That's all for now!

@Simona Griskute Hi and thanks for the answer. The same problem exactly reported kath.soa in the previous comment, namely category menu and actual post page customisations do not work. Just to be a bit more descriptive, look in the image, left on editor I customise my blog post and then when I go to preview and I navigate on my posts trying to open any of them they appear with a default and 'funny' style. This looks like a bug and I have to mention also that I haven't looked my site yet on live-published view since this is the last think I want to resolve before going live. cheers and I hope to get this fixed!

I just started yesterday building my new blog and I'm facing all these plus many more simple and basic problems, I'm not even in a mood to list them..how can this be possible!!! The old blog feels like a paradise compared to this one and I really cope that WIX will put all its effort to do something about it really soon!

Hi, the option is there (settings-go to post page-design) but it doesn't work!! I do my changes (font type and color) and when I do 'preview' it shows me a completely different, kind of default setting with black colour, the same type of font and the funniest is that the title appear small size!!! It looks really ridiculous and I'm very disappointed for such a basic problem. Help please!
