thanks I also have this issue. When I install the fixed version the icons disappear. Do you know why it might be? http://screencast.com/t/kqXUGZ78

Please download this fixed version. https://github.com/anspress/anspress/archive/9a321de6ea4641bdc1a0ca0af3ddfba96af1cf10.zip

Please deactivate and activate AnsPress again to trigger insert new mysql tables.

First of all if you have updated to beta, make sure you deactivate and again activate anspress to trigger activation hook, as AnsPress 2.4 have new DB tables.. Before 2.4 user subscriptions are stored in ap_meta table but since 2.4 there are many new tables added like activity, subscription and notification etc.. So, now most of things which need to be notified are stored in a activity table. and users subscription are stored in subscription table. And when a user need to notify about an activity then that activity id is linked with notification table.
