Thanks Michael,
I did try your suggestion however but still the same issue. The table was not present when I removed the plugin.
I then decided to re-install, dropped table, removed plugin again and then re-installed but same issue. Not shown any visible table entries, only the message “Returned entries 1 to 0 of 2 entries in the database” after I had inserted a couple of test items from my contact form.
If I go back into phpMyAdmin, I can see the two records I have entered, just not shown up in the settings page for the template.
All very weird.
