Hello,
In Xerte 3.3 upgrade.php , the function 'upgrade_5_step1' (line 330) returns with the statement:
return "Creating lti tables - ok ? " . ( $error1 ? 'true' : 'false' );
The function deals with the 'configdetails' table though, not 'lti'.
The return text should be changed to 'configdetails' (probably).
John.
