Cornerstone issue with new site

[neilhartley]

Hi,
I just started building a new site using X on Siteground. Just installing plugins. I installed Cornerstone Add New Plug-in rather than via X - then I deleted it and installed Cornerstone via the X link. Now, in the Wordpress dashboard, I keep getting this error message:

ugin_Upgrader_Skin::feedback($string) should be compatible with WP_Upgrader_Skin::feedback($string, …$args) in /home/aclrecov/public_html/whatcoloursmake.com/wp-content/themes/x/framework/functions/updates/class-x-tgmpa-integration.php on line 263

Warning: Cannot modify header information - headers already sent by (output started at /home/aclrecov/public_html/whatcoloursmake.com/wp-content/themes/x/framework/functions/updates/class-x-tgmpa-integration.php:263) in /home/aclrecov/public_html/whatcoloursmake.com/wp-admin/includes/misc.php on line 1252

Any idea what the issue is? This is my 6th or 7th X based site and I’ve had these kinds of issues before.

Thanks, Neil

Hello @neilhartley,

Thank you for the very detailed post information. I have logged in and I found out that the the X theme is not update to date. I have updated it and made sure that they are the latest (X 7.2.3 and Cornerstone 4.2.3). And then I went to the plugin section I temporarily deactivated the SG Optimizer plugin. Caching plugins and Optimizing plugins are best to turn ON when you are done building the site and ready to go live.

Please check your site again.
