Catchable fatal error: Object of class LetoDMS_Core_DatabaseAccess

[poitelodico]

This looks pretty much like a bug. I can reproduce it.

I had the same error and I fixed!
The line 1142 in inc.ClassDMS.php file was initially in this way:

$queryStr = "INSERT INTO tblCategory (name) VALUES (".$this->db-qstr($name).")";

as you can see a ">" between db-qstr is missing...
if you change the line into:

$queryStr = "INSERT INTO tblCategory (name) VALUES (".$this->db->qstr($name).")";

all will work in the correct way.
