Cannot Post to my site

I need help… Last night my site crashed. I lost all my posts & pages, but the template is still intact.

My backup is too old to use(teachable moment), so I was going to start re-posting main information… When I try to “save draft” or “publish”, it goes to “edit post” page, where it states I have “0” posts.

Same thing happens when I try to create a page…

I don’t know if this will help, but when I go into the WP-Cache Manager it has the following message:

Main options
advanced-cache.php link does not exist
Create it by executing:
ln -s /blog/wp-content/plugins/wp-cache/wp-cache-phase1.php /blog/wp-content/advanced-cache.php
in your server

Cannot continue… fix previous problems and retry

I don’t really understand code, but I can work through it with good instructions.

I need to get my site back up over this weekend….

Thanks
