Your JFFS2-partition seems full and overlayfs is mounted read-only

Hi, I don't have much knowledge in linux ad Openwrt, I tried to find solutiions on google and even here, but with no luck.

I have ssh into my router and this message appeared:

Your JFFS2-partition seems full and overlayfs is mounted read-only.
Please try to remove files from /overlay/upper/... and reboot!

seems like I cant install or remove anything.

Any help without too crazy steps.

Thanks.
