Hi there,
I’m dutch so excuse me for my poor english.
I had a simular problem getting Error code: -10520 or getting a blank page. Because i could not find a solution on any forum or any other webpage I turned to my web-hoster. They provided me with the answer to this issue.
It turned out the problem was here: wp-content/plugins/jetpack/class.jetpack.php on line 3709.
It returned this error
wp-includes/class-IXR.php): failed to open stream: No such file or directory
Although the file class-IXR.php was present in the wp-includes folder it would not load. So he made a copy of the file with all lower case and uploaded it to the wp-includes folder. Now there are 2 versions of this file present in this folder.
It works for me. Had the simular problem on a other WP install and this also worked here.
Seems a bit weird but i’m happy this issue got resolved.
Hope this might help others to adress the same issue.
