I can't get xdebug to work properly with Visual Studio Code in Linux Mint. Please help me out. I have already tried the main steps but the debugger won't stop at breakpoints or show any error message. I cant do stepping or anything proper of a debugger. The extension is installed, and the firefox helper too. The xdebug.so is in the correct directory and php.ini has the entries according to the manual. What else can I do?
