Yesterday I spent some hours updating a number of recurring events in my calendar. These took longer and longer as time went on, and I finally abandoned my updates overnight.
This morning my calendar is no longer accepting any amendments whatsoever. I can’t change any existing items, nor add new ones. More worryingly, I can now no longer add any media files or even update any of my posts or pages. It’s almost as if the whole site has siezed up. I’m also unable to activate or deactivate any plugins (so I can’t tick the box below).
I’ve run a database repair which found no problems. WP_debug found lots of issues with WP_options but I don’t understand the output.
Can anyone suggest somethings to try?
