I'm using MAMP on OSX. I exported the database and imported it locally. Created the same DB username and password as on my production forum. I then copied the entire /forums directory from my production site to my MAMP server's htdocs folder.
I edited conf_global.php to change the board_url to "http://localhost/forums". I left the DB name, username and pass all the same as these didn't change.
When I try to hit http://localhost/forums/admin/ (or just /forums/, or anything else) I get a 500 error. What am I missing or doing wrong?
EDIT: I figured it out. Looks like MAMP was trying to use PHP 7.0.0 by default. Switched it to 5.6.10 and then it worked. Well, I at least got the database error... so that's a start.
