Wrong directly constantly
 

I have my photopost in /gallery, it keeps trying to link images in "/gallerydata/" instead of "/gallery/data" I went to all "All Options" in the admin panel, and nothing was pointing at "gallerydata", since it originally was, I had to fix it. Do I need to re-run my setup again?

Solved. Just had to run the install.php again and make sure I add "/" at the end of anything that asked for a path or directory.

You could have also gone to admin global options and storage options and fixed the urls there ;)
