Search for: xb_footerBlock_css using your admin search,
in the misc box put in:
That will shift the content of the other blocks to the top. You'll will have a massive gap on the bottom but another thing you could consider is... making the facebook widget a wider shorter one that takes up 50% of the footer, disabling that 3rd column.
Yes. I am pretty sure it was fine previously. Don't know if the upgrade to XF 1.5.5 caused it or it something my end. I am trying to find the cause. Will also upgrade Xenbase and see. Will contact you if I cant solve this glitch.
