Hi, I have problem that if I edit anything in my local.config.php, the whole website crashes and I have to enter database info via install folder, otherwise the web doesnt work. My local.config.php is blank as default, when I add something in it the website shows some DB error, and when I delete the lines I have added, the website redirects me to install folder and says that I heavent installed phpvms yet. any ideas?
