Fatal error: Cannot redeclare get_avatar()

[spar303]

When I activate the vBulletin Wordpress Bridge plugin version 10.0.5.1 on my version 3.1 Wordpress install, I am getting the following error/conflict:

Fatal error: Cannot redeclare get_avatar() (previously declared in /public_html/wp-includes/pluggable.php:1618) in /public_html/wp-content/plugins/vbbridge/vbbridge.php on line 435

Has anybody else ran in to this problem?

Something tells me you are including pluggable somewhere before you should. pluggable.php is named that because those functions can be overridden.

Either it is a misconfigured theme or a bad plugin.

It was a conflicting plugin after all, however it was a plugin that I needed to keep. My solution was to make the bridge plugin load first so it can define get_avatar(), by putting this code into the bottom of vbbridge.php:

function this_plugin_first() {
    // ensure path to this file is via main wp plugin path
    $wp_path_to_this_file = preg_replace('/(.*)plugins\/(.*)$/', WP_PLUGIN_DIR."/$2", __FILE__);
    $this_plugin = plugin_basename(trim($wp_path_to_this_file));
    $active_plugins = get_option('active_plugins');
    $this_plugin_key = array_search($this_plugin, $active_plugins);
    if ($this_plugin_key) { // if it's 0 it's the first plugin already, no need to continue
        array_splice($active_plugins, $this_plugin_key, 1);
        array_unshift($active_plugins, $this_plugin);
        update_option('active_plugins', $active_plugins);
    }
}
add_action("activated_plugin", "this_plugin_first");

Hope that helps someone.
