WP recovery mode triggered by Graphene theme
This afternoon I received an email from WordPress that there was an error with my theme, Graphene. My site has been down all day; my assistant and I have been working to get it back up to no avail. I tried help with FatCow and there’s nothing they can do, that the problem is with the theme. I’m completely locked out of my site and could use some advice. I’ve pasted the error message I received below. Thanks.
An error of type E_ERROR was caused in line 1 of the file /hermes/walnacweb01/walnacweb01ac/b1034/moo.laughingatchaos/wp-content/themes/graphene/functions.php(69) : runtime-created function. Error message: Uncaught Error: Call to undefined function n5Wa0J3bwVmcfJ3byJXZ() in /hermes/walnacweb01/walnacweb01ac/b1034/moo.laughingatchaos/wp-content/themes/graphene/functions.php(69) : runtime-created function:1

The function that was mentioned in the error message
n5Wa0J3bwVmcfJ3byJXZdoes not exist in Graphene. You can see the content of the original file here:
I suspect for some reason the theme’s files on your site have been modified. A quick fix would be to ask your host support to completely replace the theme’s files and folders with a fresh copy, that can be downloaded here: https://wordpress.org/themes/graphene/
After you have regained access to the site, I would suggest to do a scan using WordFence for any potential security vulnerability.
