I used the age old workaround of no headers by moving the plugin files to the ../plugins/ folder... no problem there... also saw it in Tools and was able to navigate to it... but when i clicked on Settings I got the following errors:
Warning: require_once(/home/xxxxxxxxx/public_html/wp-content/plugins/source/../../../../wp-admin/admin.php) [function.require-once]: failed to open stream: No such file or directory in /home/xxxxxxxxx/public_html/wp-content/plugins/source/wp-link-robot-settings.php on line 2
Fatal error: require_once() [function.require]: Failed opening required '/home/xxxxxxxxx/public_html/wp-content/plugins/source/../../../../wp-admin/admin.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/xxxxxxxxx/public_html/wp-content/plugins/source/wp-link-robot-settings.php on line 2
[ xxxxxxxxx being private information ;) ]
which says to me because of the original folder mapping errors it got broken when i moved it to the main plugin folder... so this is an essentially busted plugin
