moving forum to a new server

[odonel]

ok guys, here it is. I am moving my forum to a new server. i copied the forum folder/files to the new one, i copied the database over, but when i try to access the index.php page, all i get is a blank page. on view source, this is what i get

index.php view source...
<!-- BEGIN TEMPLATE: FORUMHOME -->

<!-- END TEMPLATE: FORUMHOME -->

/admincp view source

<!-- BEGIN TEMPLATE: STANDARD_REDIRECT -->

<!-- END TEMPLATE: STANDARD_REDIRECT -->

if i used an old database from 4 months ago, it works. i think it is because of some new added plugins. some of the products i have added recently (zoints anonymous post, cyb statistic,billspaypal donate) where do i start troubleshooting ?

i use robocopy to backup my forum db. same as the one that works for the old 4mnths old db

vb ver 3.6.4
thanx...
