Sonoff Basic not responsive since v2.0-20180124

[wim16]

Today I decided to 'upgrade' my Sonoff Basic from v2.0-20180112 to v2.0-20180130 and saw that the webpages are no longer responding.
I tried several nightlies and the v2.0-20180123 is the last build that works ok; all the later builds are not working well.
The Sonoff boots normally but does not respond to web requests and also seems to loose wifi connection several times. See the serial log below.

The only visible difference between v2.0-20180123 and 24 is the change regarding DST.
And when I fall back to v2.0-20180123 it does not set system time correct, but that may be because of some config change as a result of the new DST.

It is a bit strange, since my 5 NodeMCU's are running fine on the most recent version.
Can it be caused by the difference in flash-size between these boards?

Well, it seems not a lot of people have experienced this problem too .

In the mean time a have been investigating a little myself and found that the problem is probably in _P036_framedOLED plugin.
I have compiled ESPEasy from V2.0 20180130 source and it did not work.
However, if I replace P036 with the version of 20180123 (and keep the rest on 20180130) there is no problem and the Sonoff works ok.
Strange thing is that there is no P036 device in my setup, but somehow the plugin seems to cause a problem.
Now, to find out where that problem comes from...

Since I do not intend to use P036 I may choose to keep using the older version of this plugin but I would like to be able to upgrade ESPEasy without having to customize myself.

Please add an issue on Github.

Done!

With some plugins it is possible to just leave them off.
As it is not very likely that you use an OLED with the sonoff basic
you may try just deleting it from the source folder and see if that runs.
