I am using the constant wp_plugin_url in my plugin which works nicely with wp2.6 but 2.5.1 hasn't got this constant defined.
I thought putting
if ( ! defined( 'WP_PLUGIN_URL' ) ) define( 'WP_PLUGIN_URL', WP_CONTENT_URL. '/plugins' );
would do it but the source of a 2.5.1 wordpress page is showing WP_CONTENT_URL instead of the path
is wp_content_url defined in 2.5.1? I searched high and low and couldn't find an answer :-(
is there a backwards compatible way of using wp_plugin_url as a constant?
