I upgraded a fairly large project from v5.2 to v5.3 today. I noticed that all of my grid blocks #grid_block1 are now left justified. I checked the CSS on both my 5.2 and 5.3 project and see that the CSS for those blocks are the same. I could go through and click on each grid block in the visual editor and click the center button, but I'd rather not do that if possible. I'd like to be able to change the setting in just one place so that all of my table data in grid blocks are centered on the screen. Any ideas where I can set this up?
