Problem not present in v 8.1. Only affect 8.2 in my case Build 201609300101 Classic php page with html. The warning Element "Title" must not be empty appears in both this cases: <title><?=$pageTitle ?></title> or <title><?php echo $pageTitle ?></title> maybe because the software simply checks for the presence of text between <title> and </title> excluding anything between < >. That's OK in pure HTML but with PHP could be better to consider <? ...stuff... ?> as text or, to go even further, taking into account <?=...anything...?> and <?...echo...?> (simply ignoring if php actually will print something). However for me a simple <?...?> considered as text whaterver it contains would be sufficient. By the way, same problem everywhere, e.g. <option value="1"><?= $myOption ?></option> gives a warning that "option must not be empty" To disable that nasty warning I should remove "All Other" HTML hint option but I ignore what other warnings it disables.
