Having followed the instructions in the public ticket here: https://unitecms.ticksy.com/article/12117

And successfully run the test (although the version in the test is Plugin version 1.5.18 ) I am not sure if that matters. 

I am unsure of my next steps. I have currently deactivated the plugin and the edit page works again, without the widgets, which are obviously from unlimited elements.  

I have tried to find a way to revert to the previous version of Unlimited Elements but cannot find an easy way to do this. 

Could you please advise what to try next?
