Hello I’m new to WordPress. I installed a theme yesterday, made only a couple of changes, refreshed it and it was fine last night. When I I went to the site this morning, it was all blank, so I can’t even access the dashboard or anything.
I know a bit about CSS and HTML, but nothing about database or PhP. What can I do apart from deleting it and starting again from scratch?
If you can use ftp, make a copy of the theme folder to your local PC for backup, then delete the folder on the server. That will force WP to fall back to the default theme and will probably give you access again.
