FOP2 running on FreePBX 14.0.5.2 "System is not available right now" Error
Tried to update

string (123) "256, SQL Error: DESC asterisk.parkinglot
Table 'asterisk.parkinglot' doesn't exist (/var/www/html/fop2/admin/dblib.php, 1                             08"

This condition now exists on most of my VMs

Same error here. I had to create the parkinglot table manually

mysql
use asterisk

create table parkinglot (
`id` int(11) NOT NULL AUTO_INCREMENT,
`data` varchar(30) NOT NULL,
`keyword` varchar(30) NOT NULL,
`name` varchar(20) NOT NULL,
`channel` varchar(20) NOT NULL,
`type` varchar(20) NOT NULL,
`exten` varchar(20) NOT NULL,
`context` varchar(20) NOT NULL,
`context_id` varchar(20) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=56 DEFAULT CHARSET=utf8
