JamRoom 6 Latest Activity 'Array' errors?
Using Jamroom
You both were using custom templates for the activity timeline.
Ceri, I deactivate your custom item_list.tpl in the ACP > Profiles > Timeline > Templates section. You may want to check out the new template and update your custom template to the latest code.
Holly, you were using a custom template in the Site Builder widget, I changed that back to the default template, if there was code in the custom template that you needed, let me know and I'll get that added to a new custom template for you.
Hope this helps!
