Hello,

if you take a closer look at the menu items, you will see that they point to different pages. If I remember correctly, K2 installs some menu entries as examples; so this is not an issue, it's how is supposed to be.

Just to be sure, your problem is the K2 menu entry not shown in the backend, under the Component menu, right?
Can you please check if the original site has the menu entry visible or not?
Akeeba Backup simply creates a "snapshot" of the current database state and then dumps it in the new site, there's no logic applied to the database data.

Since I spent last week debugging this issue, I might just as well chirp in this ticket :) No, Akeeba Backup has not to do with this. This is a problem with Joomla!. I'm not saying "bug" because Joomla! is not entirely at fault here.

We are able to reproduce this issue for any component installed on a Joomla! 2.5/3.x site upgraded from an earlier version of Joomla! using jUpgrade (and probably SP Upgrade, we didn't try that one). The problem is that jUpgrade screws up the IDs and aliases of the #__menu table. Joomla!, namely the adapters of JInstaller, look for very specific IDs and aliases of the parent menu items under which the new menu items will be added. Since it cannot find the parent items it creates a "hanging" and unpublished menu item node. The same applies for overwriting the menu item nodes when you update a component. JInstaller can't find the original menu item and all hell breaks loose.

I spent five hours last week debugging and stepping through that part of core Joomla! code, I am 99.9999% sure of what I'm talking about. I'd say 100% but I will leave the one in a million chance of something else going on.

With your permission I'd like to make this ticket public. I don't want people to rely on inaccurate Joomla! forum posts. Moreover, I would appreciate it if you could post on that J! forum thread and tell them what exactly is going on. I am not going to do that. Last time I tried to prove I'm not an elephant on that forum I was met with hostility. Since then I decided to never reply anything to anyone in there.

I deleted your attachment, so there aren't anymore any personal information about your site.
