Its been brought to my attention that I might be the only one able to post blogs. Well, not really able, I've just discovered a little trick to getting around all the PHP errors. I actually discovered this a couple years back when I would post a new entry but it would not show up on the sidebar for a new blog post. I've found it also works in the era of the PHP Error Wall of Death.
First, hover your mouse cursor over the Blogs button on the very top toolbar, then click on My Blog. You should see a mostly blank page with the Blog Controls toolbar. Click on Edit Entries. Even if your post hasn't shown up on the sidebar it should still be showing up as one of your entries. Simply click on the one that hasn't shown up on the sidebar as if you want to edit it. Move to the bottom of the page and click on Save and Publish again. It should make it to the sidebar now if its original date is new enough to make it. I don't know if an entry older than the bottom most post would show up as a brand new one on the top, so let's assume that it doesn't unless I'm proven wrong.
