Text strings without textdomain, impossible to translate.
Some texts are without a textdomain defined, so, the translations cannot be applied.
Follows the files and lines with this issue:
FILE: vantage/includes/admin/settings.php
LINE: 115
TEXT in file: __( 'Number of days later to remove the event after it expires')
Must be CHANGED to: __( 'Number of days later to remove the event after it expires', APP_TD )
FILE: vantage/includes/events/comments.php
LINE: 317
TEXT in file: __( 'You must be <a href="%s">logged in</a> to post a comment.' )

FILE: vantage/includes/events/comments.php
LINE: 318
TEXT in file: __( 'Logged in as <a href="%1$s">%2$s</a>. <a href="%3$s" title="Log out of this account">Log out?</a>' )
Must be CHANGED to: __( 'Logged in as <a href="%1$s">%2$s</a>. <a href="%3$s" title="Log out of this account">Log out?</a>', APP_TD )
