Error updating site info using SSO after update

Updated Discourse to v1.3.0.beta6 +20 and SSO stopped working showing this error:

Error updating information, contact site admin

I am running SSO with Wordpress using the “Official” Discourse wordpress plugin.

Looking at the logs i am getting a job exception error for the avatar URL. Not sure why its replacing my URL with “valid-host/avatar/…”:

Job exception: bad URI(is not URI?): http://valid-host/avatar/8873fecd2e0ccc4af0c54c8bdb1aab99?s=96&d=http%3A%2F%2Fgrimreapergamers.com%2Fwp-content%2Fthemes%2Fgameaddict-child%2Fimages%2Fgrg-default-avatar.png&r=x

I have posted the full log (backtrace, env) info to pastebin here: http://pastebin.com/nfgvQn3z

so digging into this a bit more it seems to only come up for users using gravatar. The $params array is pulling the right URL but for gravatar links it throws the bad uri error.

Here is what the url looks like in my array.

[avatar_url] => http://2.gravatar.com/avatar/8873fecd2e0ccc4af0c54c8bdb1aab99?s=96&d=mm&r=x

Entering this url into my browser returns the correct avatar image.

Edit: It seems Discourse does not like the parameters that are at the end of the Gravatar URL if i strip off everything after the hash for the gravatar is goes through fine.

Wondering if anyone else has this issue where Discourse does not like the parameters at the end of the URL. I think i can doctor the plugin to strip off the parameters for the url. But curious as to why it no longer accepts them.

I started to dig into this more as i was having issues with the avatar update from wordpress.

I found out that since wordpress version 4.2 it now includes its own get_avatar_url function. Not sure how this reacts with the function of the same name in the wp-discourse plugin. Removing this function and rewriting to use the wordpress function has removed my issues. It also provides a bit cleaner url for the avatar.

I created a pull request with this fix for the wp-discourse plugin.
