Thank you for all this work! The debug version should be up and live, and I've been loading the site on a couple of computers to try and generate the logs.
Apologies for my php-inexperience, but I do not believe the widget is outputting the errors to any log that I have set up (or, more likely, any log that I know where to access).
I have a 'php-error.log' file on my home/<username> of the server, but that file remains empty. I also installed Error log Monitor as a dashboard plugin, but that too has an empty log. Do I need to create a separate log file somewhere for the wp-biographia-widget.php to dump to?
On the other side of things, I ran some more tests regarding the static landing page. I changed the site to have a landing page of posts (even though there are no posts to speak of besides Hello World), and the widget had two sections: a 'Written By' (empty) and a 'About Alan' (with avatar, but no biography). This is only on the landing page. The other pages still show a blank 'contributors' section in the widget with no other data.
I went back to the widget settings, and changed it to show BOTH 'Show User's Short Biography' and 'Show User's Biography' - and the text in the from the short section appeared in the widget (but only the short biography, not the long as well...)! The text from the long biography appeared in the plugin box at the end of the posts.
I then went BACK to the widget settings, turned OFF 'Show User's Biography' (leaving only 'Show User's Short Biography' checked), and the avatar still appeared but NO text from EITHER biography appeared.
I currently have the widget with both the short and long biographies checked, and have left the posts landing page up on alanwindhausen.com, if you would like to see.
