Hey gamma42 ,
Could you send us a screenshot of your console log after the crash happens?
Could you also let us know which deletion causes the error?
Is it when you delete the page rule?

Or when you delete a condition?

P.S. Could you let us know which Buttonizer version are you currently using?
I think I remember a similar bug on one of the older versions.
Thanks!
