Php changes after upgrading from vb2 to vb3

[getthat]

Hi,

A while ago I bought a nice website which was built on vb 2.2.8. It was running very nice until I decided to upgrade my forum to vb 3.0.3.

Just to make sure I installed the whole site on a different domain to test the upgrade process. Upgrading vBulletin worked like a charm ... but unfortunately some of the php scripts don't work anymore.

An index.php and an include.php file are attached.

I guess vb 3.0.3 uses other functions than vb 2.2.8. I already found out that gettemplate is replaced by fetch_template and dooutput is replaced by print_output. If i change these functions I get no php error, but the site shows a white homepage (as if the html code is not loaded from the database). Can someone help me out here ? Is there a list of changes somewhere ?

I dont fully understand where you are coming from with this. Do you mean you havent overwritten your files?

[getthat]

Well, the files in attachment are custom-written files (not from vb), but they are using the functions from vb (and also the config.php file).

Did you copy over the templates being called on in these scripts to the new vb3 style?

[getthat]

Yes, Reeve of Shinra, I did

which of these three templates are your selfmade templates?

you can only print_output one template, as there is an exit; or something there, meaning the others wont load.
