I got a php warning from that plugin that could solve in a Webserver 520 Error message.

PHP message: PHP Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /var/www/clients/client1/web12/web/templates/layout.tpl.php:109) in /var/www/clients/client1/web12/wow/assets/plugins/custom-sidebars/inc/class-custom-sidebars-explain.php on line 55

Maybe there is something wrong in the script?

Hey there Deexgnome,

Hope you’re well today and sorry for the late response.

Can you check the JavaScript console for errors?

In Chrome go to “View -> Developer -> JavaScript Console” and in Firefox you can go to “Tools -> Web Developer -> Console”

Find information about how to open JavaScript browser console :

Let me know what JavaScript errors if any you are getting when you face this issue and which plugin/theme is causing it.

You can also just try on your development site using default WordPress theme like Twenty Fifteen and deactivating all other plugins as displayed in the following flowchart to know which theme/plugin is conflicting if any.

Please let me know what you found 🙂

Cheers,
