WordPress Prologue: Mind the Letter Case

February 4, 2008

Just installed a new WordPress with Prologue. The obvious idea is to try and use it at work as a Twitter-like communication tool for my team.

Installation from svn was flawless, but my Gravatar didn’t show up.

Gravatars are dynamically generated based on your registered email addresses. The MD5 hash of an email address is used as a unique ID for the avatar image associated with it.
The problem turned out to be that Gravatar converts emails to lower case, and so for the user accounts on your self hosted WordPress blog you must use lower case for user’s emails.
If you don’t, then you won’t get the right URI for your Gravatar’s images since the MD5 hash changes with the letter case.

At least, changing emails to lower case worked for me.

    am3n,

    I don’t think you can use Gravatar if you want the images to reside on your local network; it is not how Gravatar works.

    However, you may be able to change the code to serve your purposes.
    Have a look at prologue theme code in
    wp-content/themes/prologue/functions.php
    around line 175, where the icon image is generated.

    Regards
