Rebuilding of cache causes blank page

[Contex]

Hello, so it seems like something went wrong during the rebuilding of the cache's, this has caused the CSS of the admin panel to get all screwy but also made the main website unable to browse (just a simple blank page).

What can I do to resolve this?

Edit: Nevermind I performed a rebuilding of master data by going to /install
Thanks anyways!

Correct.

And FYI for others. If the rebuild process stalls or times out then you can just refresh it until it completes.
