Many Questions

I will start with a few:

1. Is there a demo that I can test with?
2. Does VBSEO support VB forums with a lot of hacks installed? What if it doesnt work with my forum (ScoreVille: GMAT Prep)
3. Do I need to buy a new license for every website or can I install same software for all the websites I own

1. https://www.vbseo.com/demo/
2. 99.9 % hacks are compatible with vbseo, But you do need zend or ioncube on your server for vbseo to work.
3. One License is for One Site Only.

Thanks.

What is zend / ioncube, how do I find whether the hosts have it or not. I am considering hosting the website on siteground do they have zend?

You can download our test.php script. If you do not support 1 of the 2 options (IonCube or Zend), please let us know and we may be able to assist you with the upgrade.
