Had some trouble, whilst trying to change something in the function page I came across this message from death.
I accidentally deleted or added something I shouldn’t and couldn’t access my site at all to revert the mistake. This was the second time this had happened to me but the first time I managed to delete the mistake and gained full access. The second time it happened I was unable to correct the mistake and had to turn to the world wide web. That is when I found this amazing thread from someone facing the same problem.
Thank you Harrison
