 	<p>Please remember that running any application on a developmental version of PHP can lead to strange/unexpected results which may appear to be bugs in the application (which may not be true). Therefore we recommend you upgrade to the newest stable version of PHP before running phpBB3. If you are running a developmental version of PHP please check any bugs you find on a system running a stable release before submitting.</p>
