I manage/webmaster half a dozen websites that have facebook like boxes on their index pages. These were all working fine until yesterday, when suddenly they all began to display to the right of the page (where previously they had been centered). No changes have been made to any of these pages in the last day or two, so I can't think of any reason why they would all suddenly right-align.
Some of these scripts are between "center" tags, Others are inside centered tables. But they're still displaying to the right of the page. I've tried everything I can think of to get them to display in the middle of the page again, but nothing I've tried works. I'm also curious to know why they would all suddenly lose their center alignment.
Anyone have any ideas?
Any help would be very much appreciated.
