What files did you remove?

This error is partially because either you or your web host has enabled open_basedir restrictions on your account. However the access to /Templates/ does not really make any sense unless something weird is going on like a chroot environment.

Did something change with your host environment?

Try this fix…

Check for open_basedir before reading /proc #37959
