Explanation

This is only fixing a copy pasta mistake that is in the master branch, causing the length drop-down on Monitoring page to only display then length drop-down 10 (that currently does 10) and 25 (that currently does all).

"Good" example in master branch:

mainwp/class/class-mainwp-manage-sites-list-table.php

Line 1031 in e56f849

"lengthMenu" : [ [<?php echo esc_js( $pagelength_val ); ?>, -1 ], [<?php echo esc_js( $pagelength_title ); ?>, "All" ] ],

"Copy pasta mistake" example in master branch that this pull-request fixes:

mainwp/class/class-mainwp-monitoring-sites-list-table.php

Line 705 in e56f849

"lengthMenu" : [ [<?php echo intval( $pagelength_val ); ?>, -1 ], [<?php echo esc_js( $pagelength_title ); ?>, "All" ] ],

Only changed is intval to esc_js to bring it in line with other tables code.
