Fatal error: Class 'PMA_Message' not found in /usr/local/cpanel/base/3rdparty/phpMyAdmin/lib or phpMyAdmin Fatal: PMA_Message::rawError line 233 cp

You may also get asked for a username/password and when you put in the cPanel account information you get the Fatal error.

From the looks of it the cPanel accounts user has lost connection to the MySQL or be it that it does not know what the username/password is for the account to access MySQL. There is a simple fix.

Log into WHM
SQL Services
Change MySQL DB Owner Password
Select the User from the drop down list
Either put in the cPanel User’s password or Generate a new one
Change Password.
Done.

Log back in as the cPanel User and you should have access via phpMyAdmin again.

MySQL time zone different from system time zone

In some situations, the system time zone will be different than the one in MySQL, even though MySQL is set to use the system time zone. This normally means that a user has changed the system time zone, but they haven't started MySQL to cause it to change as well.

$ date
Sun Jul 1 11:32:56 UTC 2007
mysql> show variables like '%time_zone%';
+------------------+--------+
| Variable_name | Value |
+------------------+--------+
| system_time_zone | CDT |
| time_zone | SYSTEM |
+------------------+--------+
2 rows in set (0.00 sec)
If you find yourself in this situation, just restart MySQL and the situation should be fixed:

mysql> show variables like '%time_zone%';
+------------------+--------+
| Variable_name | Value |
+------------------+--------+
| system_time_zone | UTC |
| time_zone | SYSTEM |
+------------------+--------+
2 rows in set (0.00 sec)
