root@OpenWrt:~#
I've checked that the OpenWRT AP is working as usual ... just web interface isn't working
Is your wan eth0? I can't see IP.
no, it's local area ... it is working as AP for loacal area ... the gateway to wan is the modem ...
So you haven't run opkg update from AP before?
no ... the IP I use to access access point is the one I see in br-lan
In any case if a reset can solve the problems ... I'll do
Connect AP to Internet, or make soft reset.
ok ... done reset and reboot ... Luci works but if I upload saved configurations it breaks again ...
Thanks, can you provide your /etc/config/luci as well?
This is the working one, the one I saw before was different also in syntax
root@OpenWrt:~# cat /etc/config/luci
config core 'main'
option lang 'auto'
option mediaurlbase '/luci-static/bootstrap'
option resourcebase '/luci-static/resources'
config extern 'flash_keep'
option uci '/etc/config/'
option dropbear '/etc/dropbear/'
option openvpn '/etc/openvpn/'
option passwd '/etc/passwd'
option opkg '/etc/opkg.conf'
option firewall '/etc/firewall.user'
option uploads '/lib/uci/upload/'
config internal 'languages'
config internal 'sauth'
option sessionpath '/tmp/luci-sessions'
option sessiontime '3600'
config internal 'ccache'
option enable '1'
config internal 'themes'
option Bootstrap '/luci-static/bootstrap'
config internal 'apply'
option rollback '30'
option holdoff '4'
option timeout '5'
option display '1.5'
config internal 'diag'
option dns 'openwrt.org'
option ping 'openwrt.org'
option route 'openwrt.org'
Like I said I'm a noob user. Could you give an example? Like... go to the file XPTO in the directory "XYZ" line "XXX" "find this" and replace for "this" ...
Sorry about the delay... I was out...I reflashed
No. I didn't find this file. I only locate the file "luci"
Ok lets make it easier for you.
As your already in ssh we might as well simply use a set of commands to make the change
uci set luci.themes.Bootstrap=/luci-static/bootstrap
uci set luci.main.mediaurlbase=/luci-static/bootstrap
uci commit luciEach on of the commands is a single line you type in or Copy and Paste in and press enter after each line.
Configure it manually step-by-step.
After reflashing you won't find it. It it created, when luci is updated using opkg sometimes.
Configure manually step-by-step, and next time use </> tags (Preformatted text) to keep indentation.
Thanks @solidus1983 ! 
But after I run this commands and reboot the router I received the same message.
/usr/lib/lua/luci/dispatcher.lua:234: /etc/config/luci seems to be corrupt, unable to find section 'main'
stack traceback:
[C]: in function 'assert'
/usr/lib/lua/luci/dispatcher.lua:234: in function 'dispatch'
/usr/lib/lua/luci/dispatcher.lua:127: in function </usr/lib/lua/luci/dispatcher.lua:126>
run in ssh
cat /etc/config/luci
then paste up here using the Code tag </> , it seems strange that your having this issue.
