how to remove this message? query: ...

Hi,

Thank you for reporting this. This was used only for testing. We were trying to integrate some new features and we have left accidentally a uncommented line that should be actually commented.

In customers area you can download the zip. First uninstall old version, then install this zip.

Or you can comment the line in:

components/com_grid/GridBuilder.php

in line: 326
echo '<br>Query: '. $query;

should be:
//echo '<br>Query: '. $query;

Thanks again and sorry for the mistake.

Best regards,
Viljem
