I have just updated (or tried to update) Cornerstone on my plugins page and now all I can get is a blank page with the message:
Fatal error: Can’t use method return value in write context in /home/adoreamy/public_html/wp-content/plugins/cornerstone/includes/classes/admin/class-admin.php on line 286
I cannot even get onto my WP admin Dashboard as every time I try to log in I’m sent to the same blank page - I’m not techy and whilst I’ve read about FTP on some other threads I don’t know how to use or access it?
My site is still up but isn’t working properly and I need to update it and I don’t know where to start.
