Thank's Gustav,
The trouble is when you start installing packages there's no reference to the order, nor the consequences of the action. Now you mention it, I did try to get XO wiki up and running, so it looks like that's the culprit right now. Unfortunatly XO wiki depends on a filestorage version that's not available in the current oacs release, so it does seem to be related.
I think Janine has identified the basic problem, so I feel this should be taken up to the next level!!
Although it's not a 5.2.2 issue, it might make sense to create a step by step approach, so newbies can't scew up installation , simply because they see a functionality they fancy, withouth having the basics on board to get things working from scratch. The pre-install display does not show any problems ahead so it look safe to proceed with installation
I noticed for example that by installing blogger on a clean system, it won't work,but after a few other packages, ther's no problem. Can't we create a step by step introduction?
