# [Plugin: WordPress MU Domain Mapping] Undefined index: HTTPS

 * When working in WordPress debug mode, I see the following warnings:
 * `Notice: Undefined index: HTTPS in /path/to/wordpress-mu-domain-mapping/domain_mapping.
   php on line 545`
 * `Notice: Undefined index: HTTPS in /path/to/wordpress-mu-domain-mapping/domain_mapping.
   php on line 546`
 * This was dicussed 10 months ago in [this post](http://wordpress.org/support/topic/plugin-wordpress-mu-domain-mapping-undefined-index-https?replies=3),
   but the conclusion was not really clear to me. Should I just ignore the warning
   or change the plugin code?

 * I found a few other errors in domain_mapping.php, but I can’t find a bugtracker
   or repository for it. Is there an active developer on this project that I can
   email the changes to?
 * Thanks

 * I have a few notices on my site and hope someone can help!!
 * Undefined index: path in /data/xxxxx/xx/xx/xx/xxxx/user/xxx/htdocs/wp-content/
   plugins/custom-permalinks/custom-permalinks.php on line 261
 * etc etc!
 * Also, is it unsafe to have those paths displayed publicly? I replaced the numbers
   with x’s above. Please let me know!

 * Turn off WP_DEBUG to remove the notices.
 * Are you using the latest version of the plugin?
