meetme problem DB Error: connect failed

Thank you allanlee.

There are some Web-Meetme errors, that i can confirm that all EXIST on TrixBox v2.6.2.1 (STABLE)

There is a typo in one of the .php files for Web Meetme. Go to the Linux CLI and type this in:
nano -w /var/www/html/web-meetme/user_add_sqldb.php
Press CTRL+W to search and type in 'userPassr' and press Enter. If you get taken to a result, change 'userPassr' to 'userPass' (removing the 'r' on the end). Also there is another error in Line 93 comment out $userPass = "password='$userPass'"; and insert instead $userPass = "$userPass";

ALSO A USEFUL TIP:
If you did something wrong and you have been locked out from Web-Meetme then do the following to see the meetme users and change their password and admin priviledges:
mysql -u root -p (enter your SQL root password, default is: passw0rd)
show databases;
use meetme;
show tables;
show columns from user;
select * from user;
select * from user where password is null;
update user set password=PASSWORD("newpass") where email='user_email_you_want_change_pass';

I hope i helped!
