This is odd;
I had a de-activated plugin called “supreme shortcodes”. When i activate this the telephone number in the header (defined in Banner Code For Header #4) doesn’t flicker anymore, although there is a noticeable delay before it appears.
But i still have the problem of the blog(s) briefly appearing in horizontal format before switching to 3 column vertical in the links below.
Is this a problem with the theme not handling category filtered blogs correctly?
