Hi,
I just updated the plugin and all the pages in my blog went blank.
PHP Version 5.3.19
I tued on WP_DEBUG and got this:
Parse error: syntax error, unexpected '[' in /Customer Web Sites/johnjohnston/public_html/blog/wp-content/plugins/indieweb-post-kinds/includes/Mf2/Parser.php on line 356
deleted the plugin via ftp and the site came back.
Cheers
John
