4.1.12 PL1 - Blank page in usercp and in private message...why?

[adabros]

Hi.
My route is:
4.0.3 PL 1 -> 4.0.3 PL 7 -> 4.1.12 PL1.
The forum goes all right, but when I want to go in usercp or in pm i see a blank page.
with chrome read :

Errore HTTP 500 (Internal Server Error): Si ? verificata una condizione imprevista durante il tentativo del server di soddisfare la richiesta.

The permission of usercp.php and private.php are 755.

Help.
thankz

HTTP 500 error points to the server. Do you have any mods installed? If you do, can you disasble them to rule out the possibility that this is caused by one of them?

I have already disable all plugins / hooks.
Nothin' to do.

Here is a page from the manual about troubleshooting blank or 'white' pages: https://www.vbulletin.com/docs/html/blank_pages

After this process:
Admin CP -> Maintenance -> Diagnostics -> Suspect File Versions

I found:
inside: ./modcp
usercp.php File non riconosciuto come facente parte di vBulletin
private.php File non riconosciuto come facente parte di vBulletin

WHY?

ERROR LOG:
[20-May-2012 11:59:54] PHP Fatal error: PDO: driver sqlite requires PDO API version 20060511; this is PDO version 20060409 in Unknown on line 0

It is strange as to why it will return that message as both those 2 files are part of the vBulletin default package. Can you try to reupload those 2 files again from the vb 4.1.2. pl1 and see if it would make any difference?

About the server error, try to contact your host about it.

Those files don't belong in the modcp folder, so you can delete them from there.

Good catch kh99. I missed that location part.
