Vbulletin and wordpress header and footer integration problem

So im working in a project that will have Wordpress has the main page and then vbulletin as a forum. I already connected both platforms with a plugin so the users can login either in wordpress or in vbulletin.

Now for the design part, I want the vbulletin forum page to have the wordpress header and footer, searched on google and found that that can be achieved by creating a plugin/hook in vbulletin like this:

after that just insert $wp_header in vbulletin header file.

Problem is nothing happens, all I get is "$wp_header" written on top of my vbulletin page.

EDIT:
I have my wordpress installed in a folder 'apostasgreen',
and vbulletin in the folder 'apostasgreen/forum'.
maybe my file paths are wrong?

EDIT 2:
Getting slowly there, got a few improvements after searching in google:

1. Do not use 'global_start' while creating the plugin, instead select 'global_bootstrap_init_start'.
2. I found this code so I changed it on the plugin and this time something actually shows up:

After changing this code I also added this '{vb:raw $wp_header}' to vbulletin header theme file. Now it shows like this:



I think some css code is missing here, maybe path to css files are wrong, any help here please?

well you can use Ifame for one or get a plugin in WordPress

So much high tech nerdy here i have no idea what the hells going on Oof lmfaooo

hi, were you able to integrate the wordpress registration with the vbulletin? I mean that by logging into wp you can use the forum as well and not have to register in both places.

Sorry I can't help you with a solution to what you are needing, I don't know about it, but I was always looking for a plugin that lets me do a registry integration.

I knew there was one but it was discontinued and they said it had errors .. that's why my post, I hope you have found the solution to your problem. Greetings Nikoz.
