After I upgraded my Mac from Mavericks OSX to Yosemite, my local Apache and MySQL server setup did not work anymore. Thanks to Apache localhost/~username/ not working I just got the Apache server working but my Joomla application now indicates it can't access the MySQL database; neither can the Phpmyadmin tool.
How to fix this? I've seen instructions for installing MySQL for Yosemite (https://www.computersnyou.com/3376/setup-apache-php-mysql-macosx-10-10-yosemite/) but I'm not sure whether that's the best way forward as my Joomla application still needs to access the existing MySQL db information? E.g., I don't want to lose my existing saved database info of various web applications....
