My website is http://www.marion6.org. I have been using the Graphene theme for more than 5 years.
Today, when I tried to customize Graphene settings, I got the following error message:
Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 8420 bytes) in /home/content/51/3728651/html/wordpress/wp-includes/functions.php on line 4843
I do not understand this message.
So, I tried replacing the /wordpress/wp-includes/functions.php file from a former backup but then all I got was a blank page when I selected customize.
What do I need to do?
