SirDude was kind enough to help me fix a large problem on my forum and he also advised me on how to back up.
I noticed there are several ways to back up (through PHPmyadmin, thrugh my web host, or through the control panel on the forum). SirDude recommended using PHPmyadmin.
However, once I got into PHPmyadmin, and am trying to "dump" the tables (I guess this means "back up"), I am faced with a barrage of choices...and I'm not quite sure how to proceed.
Here is a screnshot with my choices:http://www.lymecommunity.com/example1.jpg
Any advice? Which boxes to check and which drop-down menus to choose?
