Title: Plugin doesn’t work behind load balancer Last modified: September 27, 2024 --- # Plugin doesn’t work behind load balancer * Resolved [hortond](https://wordpress.org/support/users/hortond/) * (@hortond) * [1 year, 8 months ago](https://wordpress.org/support/topic/plugin-doesnt-work-behind-load-balancer/) * The site is on an internal network, you will not be able to access it. * We have a site behind an AWS load balancer. The load balancer uses http to talk to wordpress (not http**s**). * When going to the wp-admin/admin.php?page=ultimate-blocks-settings&route=welcome on the site to enable the blocks, the page is blank. * This appears to be caused by all links to ultimate blocks js and css files are http instead of https. When viewing the html source for the page, all ultimate blocks URLs start with http, where all other URLs start with http**s**. * We have many other plugins that work correctly.
