Security issue

Hi,
I have table_jx_v2.5.1.1 installed on a joomla 2.5.24 web site.
The grid is installed on a page which has an access of Special and the menu item is also set to special, so public and registered should not be able to view the grid.
But it has been brought to our attention that the grid is indeed visible to registered viewers.
Any thoughts on this problem?

Regards

Yes! that has done the trick Thank you so much Tomaz
This little trick will have many more uses.

Tomaz,

I used the fix to control access to the tables (great, thank you), however a site member search her name and the page where the table resides did come up, though no data was visible. I there any way now to make the table page completely invisible to the public?

Thanks D. Ashley
