187	<p>It appears that you have installed FeedWordPress
188	<?php echo FEEDWORDPRESS_VERSION; ?> as an upgrade to an existing installation of
189	FeedWordPress. That's no problem, but you will need to take a minute out first
190	to upgrade your database: some necessary changes in how the software keeps
191	track of posts and feeds will cause problems such as duplicate posts and broken
192	templates if we were to continue without the upgrade.</p>
193
194	<p>Note that most of FeedWordPress's functionality is temporarily disabled
195	until we have successfully completed the upgrade. Everything should begin
196	working as normal again once the upgrade is complete. There's extraordinarily
197	little chance of any damage as the result of the upgrade, but if you're paranoid
198	like me you may want to back up your database before you proceed.</p>
199
200	<p>This may take several minutes for a large installation.</p>
