If you haven’t changed anything in your WordPress configuration – such as editing your wp-config.php file – and you haven’t been messing around with your database setup, I would contact your host. Maybe there’s an issue with MySQL on your server.
There must have been problem MySQL on your server as I can see your website fine now
Looks like menu are not working reset your permalinks
Thanks zoonini. The only thing I did was make changes to one page. Didn’t touch config or setup. It didn’t disappear immediately but about six hours later. Can only assume it was my fault.
I contacted host last night and they showed me how to restore site. As govpatel says, only home page up after twelve hours restoring.
The strange thing I do not understand is when I got the data error, I could not get into my WP account either. It gave the same error. What could possibly account for that?
Terrified to mess with anything now!! How do you reset permalinks please?
Quick update. The whole site is back now. Restored from host. HOWEVER, the page that I changed – To Reserve page – is the same. I was assuming it was my changes to that page that had screwed up the site but it’s back with my changes so completely incomprehensible dissappearance of site.
