Hi I tried them all three but I am sure that I have made an error somewhere in my synthax. this one showed
Code:
[cbactivity:activity asset="mainforum.9042,mainforum.%,onlyconnected.mainforum.%,groupjive.group.%,marketplace.%,events.%,jobs.%" filters="[{"filter":"Groups","assets":"groupjive.%","users":"9042,connections","access":"1"},{"filter":"Connections","assets":"connectionsonly","users":"","access":"1"}]" /]
Please note I used your option number three below (HTML encoded) and that gave the result above.
