Formatting/Display Errors Across Multiple Devices (see screenshots_

Website link: http://esovoidguild.com

1.) Weird white bottom error only shows on IE – how to fix this?
2.) Blog date wont accommodate mobile device dimensions (halfway cut off) – how to fix?
4.) bbPress login widget in footer doesn’t respond of iPad mini and other android tabs (serious overlay and unresponsive) – how to fix this?

Any assistance would be huge! I looked all though the forum and came up with nothing :/. Additionally, when attempting to switch design to fullwidth EVERYTHING is totally jacked up (as far as formatting and position is concerned).

Thanks in advance!
