Since I needed a reliable e-commerce extension with good support, that made me look to others. I tried Hikashop for a month. Though I do think the documentation is not always very clear if you are not a programmer and I also think the interface can be more userfriendly, I found the possibilities of this extension very good and the support reliable and fast.
I now feel secure using this extension and trust that the developer is continuing the good work he has already done. So I say my money was well spent,
With my discovery of the Nonumber extensions I think I am able to improve the quality and readability of my sites. The backend interface is really user friendly and clear and the service after a slight problem was in one word excellent with an immediate adaptation of the specific extension.
I think the Nonumber extensions and tooltips are a very valuable asset for Joomla!
From your description it is not clear if you did have a problem with Akeeba Backup or Joomla!.
If you restored the backup on the *same site* as you backed up from and Akeeba Backup lost your memcached settings that is a bug and I could help you (and fixed the bug, and give you a free subscription as per our Bug Bounty policy which is posted on the top of our publicly readable support forum) should you have contacted me. But you didn't and I can neither reproduce this issue nor solve it, or even figure out if it *is* an issue.
If, however, you are restoring to a different site, the problem is not with Akeeba Backup. Akeeba Backup is only responsible for backing up and restoring your site's files and database contents. In the process it reconfigures Joomla!'s db connection information, FTP information, site information and Super Administrator logins but that's all. We can not possibly replicate Joomla!'s entire configuration page. If you have such a Joomla! configuration issue it's your responsibility to reconfigure your site.
BTW, I don't think that anyone would find it logical that a Joomla! newbie should ever use memached. This is advanced stuff, which is only required for heavy traffic websites. I suppose that no Joomla! newbie would ever have to manage such a site, but I digress.
