I try to solve an error that happens as soon im in 'sale -> bills' (backend) and set a filter critera and click to filter.
First happens nothing but after clicking around i get an error which is explaned in the 'report' folder text file:
Column not found: 1054 Unknown column 'COALESCE(CONCAT(reminder.type, reminder.status), '0')' in 'where clause'";i:1;s:5999:"#0 /web/lib/Varien/Db/Statement/Pdo/Mysql.php(110): Zend_Db_Statement_Pdo->_execute(Array)
As i know, someone installed and uninstalled some Plugins, maybe the error happens of this. Can someone help me?
