SSL website is not loading in Lightbox Plus

You might trying modifying this line in lightboxplus.php:

$g_lightbox_plus_url = plugins_url(”, __FILE__); #WP_PLUGIN_URL.’/lightbox-plus’;

Line 41 in version 2.4.6

Not sure if it’ll solve your problem with SSL, but it did with mine.

Actually, that code generated the following issue for me:

[18-Dec-2012 21:07:27 UTC] PHP Warning: Cannot modify header information – headers already sent by (output started at https://www.mywebsite.com/web/content/wp-content/plugins/lightbox-plus/lightboxplus.php:2) in https://www.mywebsite.com/web/content/wp-includes/pluggable.php on line 876

The SSL issues are fixed in the latest version.
