All of the posts and pages have disappeared from the tables on their respective dashboard pages. The top of the tables still show the number of published ones etc. but I can't access them. They can still be viewed on the website though.
I was just fixing an issue with installed plugins not showing up on the plugins page (I had to delete and reinstall them) and a couple were backup plugins (BackWPup and WPOnlineBackup) so I'm worried they have messed up the database or something.
I've already tried deactivating all of the current plugins to see if that helped, but it didn't make a difference.
The databases are managed through TalkTalk Business' website manager which is pretty horrible. If anyone is familiar with this I'd appreciate some help, thanks!
