How to clear the cache for Common Lisp?

I am using Common Lisp, SBCL, and Slime to load a system that is a web browser. The system used to work properly until a few days ago.

Now, I am still able to successfully load the system. Also, I am able to start the program. I can even use the browser to navigate on internal documents, such as the manual. However, the application freezes when I try to load web pages.

After reading possible solutions to fix this problem, one of them suggests "clearing my cache for common lisp".

I have already re-started emacs or even the PC. But the problem persists.

How am I supposed to clear my cache for Common Lisp?

Solution

I suggest to try the comma-command in the REPL: ,delete-system-fasls RET system name, aka slime-delete-system-fasls (name).
