Selfoss/WAMP downloads PHP files instead of displaying them

Commenting out AddHandler php5-cgi .php in the .htaccess file seems to have had some effect. Unfortunately now visiting Selfoss (localhost/selfoss) shows me the message "an error occured". I set the logger_level in config.ini to DEBUG and see the message

Error PDOStatement: Nom du champ 'filter' déjà utilisé

(field name 'filter' already exists)

Again, I lack foundational knowledge to dig out of this so I don't know if my first problem of being prompted to download index.php is solved yet and I'm on problem number two or not. Any help is appreciated.
