I'm having trouble with the private message and group screens - the main index pages load, but if someone tries to open a message or a group, they wind up seeing the main index page, rather than the message or group they were trying to open.

This problem did not occur when the site was relaunched.

Additionally, the administrator backend is not able to update to the latest version of Jomsocial, the update screen never appears.

Hi, Mike.

1. This is menu item issue. When you upgrading JomSocial by uninstalling it, menu items in JomSocial toolbar lost "connection" with component. Joomla! mark them as disabled and with notice: "Component 'com_community' does not exist". In order to fix it please follow this instruction:

- click on menu item in JomSocial menu in order to edit it
- when in edit mode don't change anything
- save
- menu item should be fixed
- do it for every JomSocial related menu items (if needed) in all other menus

Make sure that you fix ALL JomSocial related links that way ;) Especially check Main menu - I saw some manu items with that issue there.

This is just how Joomla! works.When you have menu item linked to component and then remove that component - menu item will be disabled like this by Joomla!. Even if you install component again it will come to the system with different id so menu items will still disabled. But for luck fix is easy, just follow steps I provided above.

2. Update link in JomSocial backend menu was deprecated. Please, download latest package from here: www.jomsocial.com/component/digistore/licenses and install iJoomla installer do be able upgrade with one click.
