I wanted to back everything up so I could then upgrade.
My old backup plugin is no longer supported, so I grabbed a new one. Went to the plugin tab, and when I clicked "activate" on the new backup plugin, I was taken to a blank white page. Every single page in my dashboard and my public blog itself is now loading as totally empty - no HTML in the source at all.
I can't decide whether to throw up or cry or install the latest version of WP without a backup and hope it's all okay. Help?
