End stops not working after upgrade to 1.19

Awesome response as usual David. Will do the 1.2 upgrade. In the meantime here is config .g.

Thanks. I didn't spot anything wrong in the config file.
Are they optical endstops? Those sometimes leak a little, often due to the carriage not completely blocking the slot, and if they don't have built-in pullup resistors then the external LED+resistor pullups in the endstop circuits may not be sufficient, resulting in no response or a slow response. In an earlier firmware version (1.18 AFAIR) I disabled the internal endstop pullups in the microprocessor to try to resolve a separate issue; but I've re-enabled them in firmware 1.20.

The end stops are mechanical except for the IR probe on Z. I have upgraded to 1.2. Now the end stops in Machine properties are hitting but the Z probe has stopped hitting however the red LED on the IR probe is still activating at the right distance from the bed.
-
I should of said end stops still not stopping X and Y axis and z still getting Insufficient axes homed for bed probing error
-
Also getting an error message when connecting on WiFi "Can't open 0:/sys/oem.json to read, error code 4"

That's normal, and you can ignore that message.
Please run M574 without parameters after a failed X or Y homing attempt and post the response here. You can reduce motor currents for now to avoid damage when homing an axis fails to stop.
What type of switch are they: simple 2-wire microswitches (in which case, why are you using the NO contacts instead of the NC ones), or the 3-wire Makerbot type?

Just a thought but it's not this is it (from the upgrade notes for 1.19)….........

Important! If you use an IR Z probe or some other type that does not need to be deployed, delete the files sys/deployprobe and sys/retractprobe.g if they exist, because they are now called automatically. You can do this in the System Files Editor of the web interface.

Thanks for the input guys. The end stops are 3 wire Makerbot. I am also getting an error on the bed heater.
Error: Temperature reading fault on heater 0: unknown temperature sensor channel
M574 reports Endstop configuration: X:low end unknown type Y: low end unknown type Z: none, -
Decided I had nothing to lose and redid the configuration with the RRF configuration tool. This has sorted out all my problems. Thanks for your time David.

I'm sorry I was a little slow in responding. The M574 "unknown type" report was caused by a firmware bug, it should have said "active low switch". This will be fixed i release 1.20.1. The heater 0 problem was caused because you didn't have a M305 command for heater 0 in config.g.

Thanks again. Happily printing now.
