I have or had in this case, two wordpress sites running on a Ubuntu 12.04 server edition which were installed over the weekend. After installation both sites were performing as expected, no problems. The mysql tables were populated and life was good.
This morning after a server restart, the mysql tables are gone and when entering the url to go to the sites wordpress is presenting the initial install page with the following appended in the url ... wp-admin/install.php.
My file permissions are as follows:
For both sites, there is a dedicated user for the purposes of the database installation and credentials to keep information separate. Everything else is separate too like the installation directories and apache config files.
Has anyone experienced this before? Are there any other thoughts on what the problem is?
Thank you for the help.
