Magento 2 Admin site not loading properly and unresponsive

I managed to clean the cache by running: cd public_html —> php bin/magento cache:clean
I am still not seeing any changes on the websites though so I wanted to make sure I’ve turned the correct ones NULL cause I think they look a bit different to me than the ones you indicated earlier. The highlighted ones have been changed to NULL:image
is this correct and it will just take some time for changes to actually be shown on the website or is there something I may have done wrong?
