Ok, i have same problem, but i made a bit of debuging and there we go:
in file logic.php function: comments_awaiting_moderation
before line:
$comments_table = $this->store->comments_table_name;
put a line:
$this->getStore(); // looks like store is not initialized yet
This will stop all SQL errors i could see, tho still doesnt work… looks like it hangs on OpenID Customer… with bad_signature error…
Tryed myopenid.com and pip.verisignlabs.com … same.. so imho there should be error deeper somewhere.
