Seems like my version of OR (so far 2.3.6) is always playing hard ball on installation issues, this comes primarily because of 2 reasons:

1. Foreign language installation sucks so I must install in English to get all the features and necessary feedback.
2. I have to deliver the solution in Spanish, so I have to make tweak in the files at some point.

Anyway, I usually get an error when testing the first listing when uploading images, to solve this problem I usually do the following:

1. Delete de default post (the one listing the White House).
2. Make sure folder permissions of that folder is 777.
3. Delete the image files of the default post.

This seems to work so far. If anything additional comes in the spotlight I’ll update this post right away. Any comments, experiences or solutions are welcome.
