Cornerstone server errors

[bmahoney59]

Hi,

I’m having a problem with my site where I’ve had an Essential Grid developer make some changes to this page: https://www.bostonhypnosis.com/client-reviews/. He can see the changes, but I can’t even after having purged all caches and turned off caching plugins. I took the problem to my hosting company and they said:

" Taking a look at the logs on your server, I show a bunch of errors with
your plugin ‘Cornerstone’, which I have included below:

AH01071: Got error 'PHP message: PHP Warning: Cannot modify header
information - headers already sent by (output started at
/home/wp_q4pvap/bostonhypnosis.com/wp-content/plugins/cornerstone/includes/classes/common/class-locator.php:1)
in
/home/wp_q4pvap/bostonhypnosis.com/wp-includes/rest-api/class-wp-rest-server.php
on line 1631PHP

This error repeats a bunch, and so I would definitely recommend getting
this looked into by your developer. It may be a contributor for why
you’re not seeing the proper content on the site if it’s breaking the
server-side caching."

Developer only did some basic work in EG, I don’t think he can help with this. Can you offer me any suggestions?

Thanks either way.

-Brian

Hello Brian,

Thanks for writing in!

It seems that you are using an older version of the theme.

Could you please update to the latest versions?
Our latest versions are:

• X theme 8.1.5
• Cornerstone 5.1.5
• WordPress 5.6.1
• PHP 7.4

This latest release contains fixes for several issues so be sure to check out the changelog:

• https://theme.co/docs/changelog/x-8
• https://theme.co/docs/changelog/cornerstone-5

After doing the updates, always remember to clear all caches (if you are using WP Rocket, WP SuperCache or W3 Total Cache) when updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.

Please let us know how it goes.
