Wouldn't be possible without breaching several laws, unfortunately. I'd write a guide but there was more extensive things I added like using filp/whoops for error pages instead of the built-in vB error handler, and it would take forever to filter things like that out.

New licenses can't even download vBulletin 4.x

So, you're either doing all this for existing customers who refuse to move on ...

or you're wasting your time.

This is an advantage, not disadvantage. No updates means no extra work to adjust my code with any new release.
Even if there are some of them, I mainly do it for my own use and pleasure.
Be sure that I'm not wasting my time :) There are thousands left alone in the ship. Even for vB3. Do you know how many new Admins started a forum with vBulletin latelly? When they can find a license for less than $50, why not give a try?

In fairness, I think people are more likely to want to stick with vB4 than upgrade and move over to the absolute mess that is vB5.

vB5 is not "a mess" but you would have to be using it to know that.

Only if you want to use it just for forum.

I Added a Thread on your forum with all the bugs i found
take a look :)

Give a couple of hours to test it :) Have stressed myself to finish the extra features today, and I'm feeling so weak now. Most probably i'll check it tomorrow morning (in around 14h from now).

Just finished "everything" https://vborg.vbsupport.ru/data:imag...ABAAEAAAIBRAA7 ... Well, to be more specific, that "everything" at this time has a general meaning.

This project started with focus to be a responsive vB4 style. This done. Also my intention was to give a fresh style (simple style), with focus to "Mobile first". I believe that this also done. Third plan was to release some extra features like:

• Cookies Policy
• GDPR compliance features
• Modal Profile with basic member info
• Modal Login/Register
• A simple Mailinglist
• A simple Donation form with IPN support
• HTML system emails
• A powerful Footer section
• Memberlist replacement

All of them added and at least in my test, seem to work fine. The problem is that some of these features were plan for the PRO version. I'll think how to resolve this.

What is still missing:

• RTL currently is partial supported
• Forum only version works. So the Suite version is still unsupported
• Even if all pages are responsive, some of them are still with the old interface. Responsive but not updated. Maybe I missed a couple of pages, but is so hard to check all of them. This can be done only in real use. What I care most, is to have all member links in all pages, opening the modal window. For sure in the most important pages this works, but needs very deep check to find what left out.

Thanks Christeris,
I love this project, however I got this message after installed. any idea why?
