I think the problem might be the template, since the error is about eval() function which is used to fetch templates.

Can you setup other tabs to see if they work? It seems to work fine with the error. If the error is not affecting, we can put an "@" in front of eval() and it'll hide the error.

Since I and my friends don't have this problem (tested on 3.7.0, 3.7.1) so I'm not sure how to fix this.

Where do i put the "@" in front of?

Uhm let's try this: Open tabs.php,

You will see function eval(), since we don't know which function causes the error so just put @ in front of all eval().

For example: @eval('bla bla bla');

Let's see how it works :D

Yup, it's hidden now... but there's a space between the tabs and the forums shown :(
Could that go away and the tabs "buttons" made bigger?

Cool! But I didn't see the space between the tabs and the forums

You can edit the CSS, edit li properties, set a line-height:18px (or higher).

You also need to modify the template tabs_forumhome because your forum is using not standard template, it uses splited category template.

Okay, thanks a lot for the nice support NsT... your gonna do good here on vB.org ;)

Later Edit: I set the li to 30px and it's perfect :)
Thanks again... now i gotta find what's causing the gap :p

You're welcome Magnumutz :D I'll try to help out as much as I can :p

the instructions is just too much. cant you provide product instead, I wont install until theres such feature

I don't think the instruction is too much because you just need to create 3 new templates win a few minutes, and then upload some files and setup your tabs. Probably it will take you abou 5 minutes to do this mod.

But anyway, this script is not for one who wants plug & play :D

i hope i don't get banned for this question :)
but can i pay a little bit to someone to install it to my forum? pm me :)
thanks
