As an outrageously new newbie to dolphin I have been struggling along with the fantastic support provided here in the forum. I just went through a new issue and was completely panicked. The footer suddenly appeared in the right column with the boonex footer under the Join/Login buttons. I found a couple of very negative notes in the forum referencing the footer (tampering is highly frowned upon, even if you were not tampering). Anyway, I was adding a new block to the homepage when this happened (along with some updates to language keys) etc. I found the error occurred only when logged out. Once logged in the footer moved back to its proper locate.
Long story short, I added <div class="usualHeader"> to a new sentence I wanted bold in the ‘Not a member yet?’ block. Once I removed it all was well.
Not sure if anyone cares but if it happens to someone else perhaps my words can save them some time.
