Hi,
I'm on Joomla 1.5.15, PHP 5.26, JoomlaComment 4.0 RC1, mysql 5.0.75.

My new installation of JoomlaComment is only set to appear on certain pages and be commentable by registered users.

When one is not logged in, the page in question appears fine and displays the "Only Registered Users Can write comments" message.

But once I sign in, that same page displays a 500 Server Error.

I've turned off Joomla's built in SEF facility.

Does this point to any likely problem?

I've searched the forum but don't see other cases like this.

Thanks for any help.
Greg
