Topic: Bug in pun_include
PunBB does not check that the pun_include statement is inside brackets. If you leave out the brackets, the loop will continue indefinitely. In footer.php, line 143, I suggest you change the code from
while (preg_match('<pun_include "(.*?)">', $tpl_main, $cur_include))
{
ob_start();
include PUN_ROOT.$cur_include[1];
$tpl_temp = ob_get_contents();
$tpl_main = str_replace('<'.$cur_include[0].'>', $tpl_temp, $tpl_main);
ob_end_clean();
}to
while (preg_match('/<pun_include "(.*?)">/', $tpl_main, $cur_include))
{
ob_start();
include PUN_ROOT.$cur_include[1];
$tpl_temp = ob_get_contents();
$tpl_main = str_replace($cur_include[0], $tpl_temp, $tpl_main);
ob_end_clean();
}I hope I didn't get it wrong now again 
I had no idea < and > were valid delimiters. That's probably why I never noticed the error. Thanks for the report.
