Taking over a CI based site

[eluser]Unknown[/eluser]
newbie question.

i am a web developer who is taking over a site that is based around the codeignite framework. i have never worked within this until now but i like what i am seeing. i am setting up a codeignite install on my server to play with, but when i go over to my client's current site i do not know where to start to make changes.

the previous developer has locked them out of making changes beyond text swaps via the frotn end.

can someone give me some guidance on where/how i can access the deeper backend admin type functions?

i know this is an entry level question but after poking around the forums and the user guide im still a bit lost.

any help is appriciated,
thanks

There are no default frontend / backend functions in codeigniter, so everything you can access online is custom.

To make changes around that, download the source code, specifically the application directory. Within that is the actual code making the site work, the views, models, controllers, etc.
