I have a few pages that use the column shortcodes, I'm using the one_half/one_half_last pair, and using the one_third/one_third/one_third_last set. Today I found that the one_third shortcodes no longer work, but the one_half ones do. The only things I've updated have been Ultimate TinyMCE and Better WP Security. I disable U-TinyMCE and the problem persists, so the only other thing I can think of would be Better WP Security.
Is there some way that I can eliminate the Better WP Security update as the cause of this problem, other than disabling the plugin? Since I was hacked a few weeks ago I'm a lot more paranoid and don't want to be without BWPS for long.
