Hello, ronycandeli and xx.
Thank you for you reporting, ronycandeli.
I haven't tested this plugin on WebMatrix environment. But let's try trouble shooting. Will you give me more information about your environment?
- Check if sqlite-integration folder is placed under the plugins folder.
- When you put db.php file under the wp-content folder and accessed WordPress site with your browser, were there any error mesages? Or only white page?
- Check if your PHP has loaded the required extensions.
You wrote about the activation, so #1 is OK, I guess. In fact, activate or not won't affect the database management process of the plugin. As for #2, WordPress loaded db.php file, but didn't execute something.
Do you know how to check #3? Does WebMatrix have some utility for checking PHP infos? If not, please create a file like below in the server root and access it with your browser.
Check if there are PDO section and PDO sqlite driver. If you don't see that section, you can't use SQLite database and SQLite Integration won't work at all.
Thank you and good luck.
