jreklundI would start by upgrading to Codeigniter 3 and take it from there.

Hi, thanks for your reply.
I've done an upgraded test version of the install in an copy of the original folder, but there seemed to become more errors since the project is started to be written in 2011 and there seems to be some code that has to be updated in controllers and models to get it to work flawless, so I feel I have to be more comfortable with the installation as it is right now and get the Administrator part of it to work to see what is working there and what's not.

According to the developer it should work but she had "forgotten" the log in, and have not heard from her in over a year.
So I'd like to get that part figured out, there is administrator_model.php and administrator.php controller in the aplication folder, and an folder with linked administrator views in an application/administrator folder called old_views, but not in the current application/views folder.
So I'm trying to figure out how and what she has been up to with a couple of folders here and there with the prefix old_.
