After that, I reboot the router. If I try to open luci now, I see the folloing error:
/usr/lib/lua/luci/controller/firewall.lua:9: attempt to call global 'view' (a nil value)
stack traceback:
/usr/lib/lua/luci/controller/firewall.lua:9: in function 'v'
/usr/lib/lua/luci/dispatcher.lua:617: in function 'createtree'
/usr/lib/lua/luci/dispatcher.lua:262: in function 'dispatch'
/usr/lib/lua/luci/dispatcher.lua:127: in function </usr/lib/lua/luci/dispatcher.lua:126>
The router is running fine, but I hope someone can help me to bring back luci to work.
So, what should I say? What a fantastic piece of software. I did a backup via ssh. Soft reset and restore my backup. Everything is fine again after 15 minutes of work. Thanks for your help and in the future I know, what I should not do...
