OK, so I was editing my functions.php file in Wordpress (on my child theme) and i removed a line of code (I copied the code before removing it). This caused the white screen of death, so I simply pasted back in the code I had removed (yes, I pasted it back in the exact place I removed it from), but I still have the white death screen.
I have taken the functions.php file from a backup I completed last week (fully functioning) and uploaded this to the correct folder through FTP, but nothing is working.
I have gone and managed to activate the parent theme again, and have created another child theme so I could compare the 2 functions.php files (compare the brand new, functioning, child theme with the original child theme that is no longer working) and the code looks to be identical.
I have even copied the code from the currently functioning child theme to the non-functioning version, and nothing changes..
I would like to try and keep the child theme that isn't currently working because I have spent all day today making alterations to the styling and dont have a backup for this yet (i know, i know...)
any handy tips would be very much appreciated.
