通过ip进入网页报错：

/usr/lib/lua/luci/dispatcher.lua:461: bad argument #1 to 'pairs' (table expected, got nil)
stack traceback:
    [C]: in function 'pairs'
    /usr/lib/lua/luci/dispatcher.lua:461: in function 'createtree'
    /usr/lib/lua/luci/dispatcher.lua:171: in function 'dispatch'
    /usr/lib/lua/luci/dispatcher.lua:109: in function </usr/lib/lua/luci/dispatcher.lua:108>

解决方法：
ssh进入机器，

rm -r /tmp/luci-indexcache

刷新浏览器即可
