Activity replies disappear on refresh (with reward)

Ok, not getting much joy here and it’s turning into a huge waste of time, so I’m adding in a reward for the first solution.

The basics:

– using WordPress 3.3.1.

– buddypress Version 1.5.5

– BP Social child theme (also tested on Default 1.5.5.

– Plugins activated – only Buddypress.

– url – (registration is open if you need to create a test account)

The issue:

When a user replies to an activity status the comment appears to have registered and the user who is replied to gets an email notification. However, when the comment is refreshed the users’ replies disappear.

The screenshots:

Comment appears before refresh –

Comment after refresh has disappeared –

Comment appears on user’s own activity stream –

The reward:

I really need this sorting and I appreciate that everyone is busy so I’m prepared to make an instant payment of £50 for the first person who can solve the issue so that the site works again! If you need more info please email info AT
