WordPress4.3 has come.

   Obon was over. This year, we, I mean my mother’s side of the family, had a party on Aug. 15 again. At the morning, my digital camera EX-V7 broke. Grrr, the timing was very bad. So, I gave up to take pictures of the party. The camera gave me the error message 「手ブレ補正ユニットが使用できません」. On the Net, I found this error is very popular one for EX-V7 and the repair charge maybe comes with a big price tag. I had the camera on 2007 Jul. 9, which is 8 years ago. I should get a new one!! Right?
   I ordered DSC-WX220 to Amazon the day before yesterday. A little while ago, 佐川さん delivered it to me, ( ›◡ु‹ ).

   Well, I’ll return to the subject.

   This morning, WordPress4.3 came. At the same time, I had some updates about a few plugins. I updated the plugins before upgrading WordPress, of course I need to back up my site data because this WordPress is a major upgrade. Usually, I update the plugins before WordPress. If you use the plugins which are not supported by authors anymore, I think you’d better deactivate them before upgrading WordPress.

   WordPress4.3 has several new features. They seem to improve preparedness for PHP7. After upgrading, I need Upgrade Network because my WordPress is a multisite type. As I use a self-signed certificate, I must to add my CA cert data to wp-includes/certificates/ca-bundle.crt before Upgrade Network. I also need to add the following lines to wp-includes/class-http.php because I use client authentication.

  • curl_setopt( $handle, CURLOPT_SSLCERT, 'the exact path of clientcert.pem' );
    curl_setopt( $handle, CURLOPT_SSLKEY, 'the exact path of clientkey.pem' );

   See The solution of “SSL3_READ_BYTES:sslv3 alert handshake failure” on WordPress.

   By the way, we have another critical patch from MS today, which is MS15-093. They say the vulnerability is critical. You’d better use Windows Update as soon as possible.
