Thank you Andrew for posting your solution which does not require editing the core.

I had the problem in 4.5.2 and fixed it by editing wp-includes/canonical.php because it needed to be fixed immediately. But then an upgrade to 4.5.3 brought the problem back.

Disabling the canonical redirect on the home page should survive upgrades.

And maybe WordPress will eventually fix the bug?

Thank you nddery, that thread you linked to contained fixes for the errors I was seeing. It seems as if the fixes are not very difficult, but the plugin just hasn’t been updated in a while.

If one is using version 0.9.5.2 of user-photo, then patching it is not so difficult. Here is the reader’s digest version.

1. Change this line:

load_plugin_textdomain('user-photo', PLUGINDIR . '/user-photo/localization');

…to this:

load_plugin_textdomain('user-photo', false, dirname( plugin_basename( __FILE__ ) ) . '/localization/');

2. Change this line:

add_options_page('User Photo', 'User Photo', 8, __FILE__, 'userphoto_options_page');

…to this:

add_options_page('User Photo', 'User Photo', 'add_users', __FILE__, 'userphoto_options_page');

Patching the plugin will only work as long as you don’t update the plugin. More information and ideas can be found in the thread that nddery linked to above.
