blank page when installing mods

[malluland]

Hello

I am on a 3.8 Vb, But When ever i install 3.7 or 4.0 (which are compatiable with 3.8 ) i get blank pages while submiting a thread or reply. And also while reading a unread thread.

For Example I installed Post Thank you Hack > https://vborg.vbsupport.ru/showthread.php?t=231666 .... when it is enabled i get blank page while opening unread PMs

And Cyb - ChatBox - i get blank page when submiting a thread or reply.

please help me

Thanks
