Upgrade Validation error SQLite

[magaa]

Baikal version: 0.8/0.7.2

• I have searched open and closed issues for duplicates
• I have installed the release zip, not the source code zip
• I have moved the whole, untouched Specific and config (no config folder in 0.6.1) folders to the new installation

Problem:
I want to upgrade my Beikal 0.6.1 installation. I tried upgrading to 0.8 an 0.7.2.
I get the following error wen i try to add the sqlite database. Hope you can help me, thanks.

This is a problem with the server setup, not with Baikal. You just need to install the pdo driver.
