Steps to reproduce

flash current git version of dev_4096, (reset settings with reset command)
connect to wlan
go to devices tab, select ina219 plugin, give it a name and click submit

-> i get ERR_EMPTY_RESPONSE in Google Chrome, same in Microsoft Edge

with the developer tools in chrome i see that i get no contend, if click refresh it loads find and the changed settings are remembered

Does the problem presist after powering off and on? (just resetting isnt enough sometimes)
yes

Expected behavior

i should directly get a page, not only after reloading

Actual behavior

ERR_EMPTY_RESPONSE

System configuration

Hardware: Wemos D1 R2

Software or git version: latest git

have this problem also with the oled plugin...

i suspect that this happens since the changes in the gui where done, but i am not sure about that...
