   Seeing this while doing a Network Upgrade

   Warning! Problem updating https://domain.tld/blogname. Your server may not be able to connect to sites running on it. Error message: SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

   The site is entirely SSL only and using a self-signed certificate.
   Running 3.1-RC5-17466
   Any ideas to fix ?
   Thanks

   We had the same situation, the solution is:

   Create a MU plugin with the following content

   <?php
   add_filter('https_ssl_verify', '__return_false');
   add_filter('https_local_ssl_verify', '__return_false');
   ?>

   and try again. :)

   Damn, this works like a charm! I was looking for something like this since I migrated to WP3.0, thanks!

   Thanks mastermind, you have just made a lot of people very happy!

   I was trying to migrate from Multisite 3.0.x to 3.1.2 and this allowed a successful network upgrade (I was already bracing myself for a blog by blog upgrade).

   The only comment I have is that the folder in which Mu plugins resides should be called wp-content/mu-plugins and it may need to be manually created as newer wp versions do not seem to include it.

   Yeah, it was included in WordPress MU, but not in the merged version.

   Mind, it'll run in SingleSite as well as MultiSite ;D
