I have tried to install livewall but an error come out.
I have my forum with Mariadb database, I don't know if this is important.

PHP Code:

Database error in vBulletin 4.2.4:

Invalid SQL:

 REPLACE INTO `vb4_dbtech_livewall_contenttype` 
  (`contenttypeid`, `title`, `active`, `filename`)
 VALUES
  ('dbtreview_add_comm', '[DBTech] Review Add Comment', '1', 'dbtech/livewall/contenttypes/dbtreview_add_comm.php');
