I have done all (?) the searching you recommend, and tried everything (?) but I am unable to solve this problem. I changed my Gravatar picture, but the new one does not show for my blog title line (actually I have two blogs). It shows in My account global and when I make comments. What have I done wrong or maybe not done? I have tried uploading through Gravatar also. I have deleted the old Gravatar picture. I did all this a couple of weeks ago so it is not the "natural" delay in WordPress that I read about.
Any suggestions will be appreciated - thanks.
The blog I need help with is jannebless.wordpress.com.
