php error then exits
when running get-map-info.php from the command line i get the following error:
PHP Warning: mysqli_num_rows() expects parameter 1 to be mysqli_result, boolean given in /opt/meshmap/scripts/checkDB.inc on line 8
after that it immediately exits and gives no further output and no updates to the db. i have the correct credentials in the user-settings.ini and the user has the correct permissions for the db. this is on a ubuntu 18.04 server with php7.2 all necessary dependencies are also installed. I couldn't find a log with anything meaningful. What are the next steps in figuring this out?
