I am not able to see the Episerver add-ons next to cms in the episerver header. Is there something i need to do or install to be able to do that? OR can i add my add on in some other way?
You can install add-ons directly from Visual Studio: http://world.episerver.com/documentation/Items/Developers-Guide/EPiServer-CMS/8/add-ons/Installing-add-ons/
Catrin, to see the Add-On store link in the header, your user must be in the virtual group "PackagingAdmins". You should find the following in your episerverframework.config:
<add name="PackagingAdmins" roles="WebAdmins, Administrators" mode="Any" type="EPiServer.Security.MappedRole, EPiServer.Framework" />
(See related forum post)
If your user is not part of the default WebAdmins or Administrators roles, add whichever roles (from WindowsMembershipProvider or SqlMembershipProvider) that you need, e.g:
<add name="PackagingAdmins" roles="WebAdmins, Administrators, MyAddonGroup" mode="Any" type="EPiServer.Security.MappedRole, EPiServer.Framework" />
Nowadays, the Add-On Store UI is mostly useful for seeing which add-ons are installed. You should, as @David says, install add-ons from Visual Studio (to make sure all add-ons are included with the source code of the site).
Thank you, but i can still not see the options add one when I am in Episerver, something else that i need to fix?
