The fanfictions on the site are still there and can still be read. It is just that they don't show up when browsing anymore. So if you were already reading one, you can keep reading it. Also, you can search by name if you already knew the name of the story you want to read. So, not all hope is yet lost.
If you want a fic to tide you over while webnovel works on fixing their stuff, I can shamelessly recommend my own fanfiction which I wrote for novel Release that Witch, also on this site. It is completed and over 100k words, so it could fill your need for a little while. The name of my fic is called A Helping Hand.
