first up….what happened to your site’s layout. It looks almost like the stylesheet is missing because the layout and everything is all over (broken). :whistle:
As for the title part…I’ve discovered that there have been the odd plugin widget from a third party that doesn’t work with the Remove Title plugin. Generally this means someone is not following coding standards. However, there should be no grey box if you leave the title out.
I will take a look again at your site but you will want to check into the broken layout and styling that appears to be missing on everything.
As for a boxed style layout, this theme doesn’t have that option so you would need to jump into some coding to do that.
