I have just installed by Blog on a new server and it went in and updated as it should without any problems.
My own choice of style is one that I downloaded from the Wolt Plugins page, it has a nice all white clean look, I was able to make various adjustments in the editor but when it came to changing the font and hitting 'Submit' I was redirected to my websites front page. I tried this a number of times with the same result.
So, I changed the style back to the Wolt default style and tried to change the font on that, same result when I hit submit I get redirected the my websites front page.
Any ideas ?
