Question:
How can I clear my cache files manually?
Answer:
Using an FTP/sFTP program, delete all the files and folders in the /system/cache folder except for the index.html file in the root.
NOTE: If you are using ExpressionEngine 2.)PB, you’d delete the files and folders in the /system/expressionengine/cache folder, except for index.html and .htaccess found in the root.
