Go in your cpanel and locate the cache folder. Some time when you delete cache plugin the cache pages are saved in deference folder that still active ,
if you locate that folder delete.
Or the must save way to go if you have backup your site use it .
ALWAYS MAKE WEEKLY BACKUP OR EVEN IF YOUR SERVER ALLOW IT DAILY.
