@acf-support Thanks for your answer, I’m now just getting a white screen. WP_DEBUG hasn’t done anything. Does it work on the wordpress back end? Nothing is shown either on the screen or in the log file.
There is a lot of content in the fields, I don’t want to have to type it all in again if I can avoid it. Is there any way to back up what’s contained within the fields, along with the fields themselves? Or could that be what’s causing this?
Cheers,
Govi
