Dynamic lighting seems to have stopped working

Hi I have been playing my campaign for a few weeks now and all is great but I went into it today to prepare for this weeks game and I cannot get dynamic lighting to work. The dynamic lighting layer is there and the page settings allow me to set the mask and its opacity, but none of the tokens emit light no matter what I do to them. This is doubly weird as the pages that were working fine last week are not working now with no changes to them. I have cleared my cache and disabled all extensions as mentioned in troubleshooting, but am using exact same browser and system as before. Any help appreciated

That's weird. I assume you've verified the settings for the page? You don't have fog of war on, do you?

Nope no fog of war ticked and settings are as they were and also I have re-verified on other pages. very weird - like I say been working for several weeks just fine. Any debug info I can provide do you know?

So it seems to be fine with Firefox but broken with the version of chrome I am using - must have been a last update from Ubuntu Can the Devs check out why Version 36.0.1985.125

You should post the contents of your console log, that will probably help people debug it.

Yes, if you could post the contents of the console log, that would be helpful.
