How to complete downgrade from vB4 to vB3 ?

[Kevin D.]

Hello everyone,

I'm using vBulletin version 4, my forum language is Vietnamese (UTF8).

I'm really hate this version of vB because of the mess of code and very slow.

When I used some methods to downgrade to version 3, it's always get font error, the posts can't be read.

Do you know any way to downgrade it for complete? I dont want to convert to other forum scripts.

Please help me.

Unfortunately unless one of our users has experience with this we won't be able to help you. I would say you might have better off posting on the Jelsoft forums however I don't know how they'll take to downgrading to v3 from v4 (as v4 was a big release for them).

What methods have you used?

I have used this way:

First I've back up the current version (vb4) by the same tables as vb3 use it, i mean what tables vb3 uses i'll back it up.

Then i installed a new vb3 and restored those tables into it.

After that, i used 'tools.php' (as jelsoft provided) to reimport the default English language.
