songtra on "Vowels changed into square shapes"

Hi everyone,

Yesterday, about half of all the vowels in my blog have changed shape - look like big squares. So please tell me why is it and how to fix it.

My blog is written in my mother-tongue language which is also Latin alphabet, just like English. So I think you should have a peek at my blog in order to understand clearly what I meant.

Thanks very much in advance for your insights.
