Custom page accessing the DB, access denied for user

[theyland]

Hello,
I created a custom page, which queries the database and everything works like a charm, yet seemingly only for the administrator.
When I log in, as a regular user, the table can be seen ( I did put ['*'] as group in links-home.php), but just displays the access denied message.
is this, because the DB is accessed? Can it be changed?
Thanks
Thomas

Sincerest apologies, they say, there is nothing like a stupid question! Well, yes, they do exist.

Of course, I did not grant access in the custom page.php.
That is corrected now, ignore thread.
