Well that was interesting.
I had created a pull after modifying the Functions.inc file. After deciding that the mod did not do what I wanted, I changed the file back the original state but it appears that since the poll was created with that modification, the site went down. Changing the file to the modified state, deleting the poll and then changing it back worked.
>Breathing a sigh of relief - all is well with the world again - although polls still do not show on the front page unless logged out.
