SQL ERROR [ mysqli ]

'phpbb_sessions' is marked as crashed and should be repaired [145]
The first thing that I did was to access phpMyAdmin to try an repair the table with the SQL command:
REPAIR TABLE 'phpbb_sessions'
Unfortunately, that does not work. I did some research online and finally, I managed to resolve the issue. It takes a bit of tweaking nonetheless, but it's a fairly simple procedure.
Solution to Resolve phpBB error
If you have access to phpMyAdmin application, under cPanel (from your web hosting service provider), then it would make things a lot simpler.
- Under your control panel , click on phpMyAdmin icon.

Next, click on SQL, located that top of the phpMyAdmin application. This will then open up the dialog box.

- In the dialog box (shown below), type in the following SQL command.

SQL Code BelowDROP TABLE IF EXISTS phpbb_sessions;
CREATE TABLE phpbb_sessions (
session_id binary(32) DEFAULT '' NOT NULL,
session_user_id mediumint(8) UNSIGNED DEFAULT '0' NOT NULL,
session_forum_id mediumint(8) UNSIGNED DEFAULT '0' NOT NULL,
session_last_visit int(11) UNSIGNED DEFAULT '0' NOT NULL,
session_start int(11) UNSIGNED DEFAULT '0' NOT NULL,
session_time int(11) UNSIGNED DEFAULT '0' NOT NULL,
session_ip varbinary(40) DEFAULT '' NOT NULL,
session_browser varbinary(150) DEFAULT '' NOT NULL,
session_forwarded_for varbinary(255) DEFAULT '' NOT NULL,
session_page blob NOT NULL,
session_viewonline tinyint(1) UNSIGNED DEFAULT '1' NOT NULL,
session_autologin tinyint(1) UNSIGNED DEFAULT '0' NOT NULL,
session_admin tinyint(1) UNSIGNED DEFAULT '0' NOT NULL,
PRIMARY KEY (session_id),
KEY session_time (session_time),
KEY session_user_id (session_user_id),
KEY session_fid (session_forum_id)
);
- The above code will typically delete the 'phpbb_sessions' table and re-create a new one.
Fixed..!
