This is very weird.. I'm wondering if I have been hacked. But I worked on my site for a few hours, all things were fine, went to sleep and when I came back the theme that I was working on was no longer there. The site reverted to my old theme, and a plugin I was using -- Maintenance Mode -- was missing as well. My dashboard settings had been changed. The theme is still present in the WP-CONTENT folder, yet I cannot access it. HELP?!
