Hi,
I have just updated the X theme to the latest version and that all went fine. The problem comes when I try the Cornerstone update. After trying this I just get a white page when looking at my dashboard and the site has gone a bit screwy on the headlines.
I have left things as they are for now, hopefully it won’t take you long to take a look.
I checked the best practises and have WP-debug set to true and am using PHP 7.01. Sorry not very easy to set a staging enviroment, have tried it before via the siteground system and it didn’t seem to work very well. Changing things on the staging copy ended up changing stuff on the live site anyway.
Edit to add: There appears to be a problem with Envira Gallery related to the latest Cornerstone.
Regards,
Mark
