This error is definitely from your php.ini, please uncomment or enable the extensions for SQLite3 inside it.

 

Where can I find php.ini?

 

In the same folder as your PHP binaries. Even though SQLite3 is included by default with PHP, on Windows it seems you have to manually add these entries to php.ini (or remove the semicolon if these lines start with a semicolon):

Code:

extension=php_pdo.dll
extension=php_sqlite3.dll

Also see here

 

I still don't understand...What are the lines I should edit?

 

You should just add the lines Awazaw posted on the bottom of the php.ini file. Did you find the file?
