Luci is broken after opkg upgrade.
I have installed OpenWRT 18.06.2 on TP-Link TL-WDR4900v1 several months ago and everything worked well until last week when i decide to update luci packages.
I updated Luci with the latest version (checked with "opkg list-upgradable") and after that luci does not work anymore, I got the following error:
# Bad Gateway The process did not produce any response
I noticed that in the last few months you released many Luci updates, honestly I don't understand what are you doing, do you check new package releases before putting them in production?
Please help me to have Luci working againg without having to reinstall everything.
