Autofocus stopped working on 1 lens only

[unsure]

Hi all,

I'll start by saying I'm new to Magic Lantern & have only been a user for a week or so. Everything I've used thus far has been fantastic & thank you for providing such a great piece of firmware.

Today, I went to use my Canon 50MM 1.8 to take some headshots & the autofocus was not working.

Upon pushing the shutter half way, it would just tick & try to find focus however never did. I've tried using the AF-ON button & also resetting custom settings back to default.

I've tested this lens on a friends camera with no issues at all. I've also tried other lenses of mine & had no problems with autofocus whatsoever.

My camera is a Canon 7D.

Any suggestions or feedback would be greatly appreciated.

Thank you very much.

UPDATE: Fixed by removing & reinserting battery.
