I created a site a few months ago, setting up the infrastructure etc.
I just went in now to add content, and all of my options to do anything have disappeared (nothing on Dashboard, no Appearance tab, no Pages etc).
In addition, there is an error message:
Warning! WP Super Cache caching broken! The script advanced-cache.php could not load wp-cache-phase1.php.
I have a feeling that the problem is that I should not have allowed the automatic upgrade of the site. Am I right?
What can I do now? Do I have any other options other than starting again? And how do I start again?
