I’ve installed 4.0.2.2 and indeed the install complaint is gone. Good job. ??
But now AAPro’s options page is broken. I choose the Configuration link from WP’s plugins page. AAPro displays links to AAPro and Google 404, then there’s the characters “‘;”, then an H2 reading “AskApache Password Protect,” and then blank. In FireFox’s view source I can see the form tag, then a couple hidden input fields (the last being:
<input type="hidden" name="_wp_http_referer" value="/talk/3l/wp-admin/options-general.php?page=askapache-password-protect.php" />
There’s nothing more after that. So I’d guess either a malformed concatenation or premature end to some running code.
