Please excuse me for repeating this reply. I could avoid it if I knew how to delete this second box.
I have deleted and uploaded.
The Full Package instructions say "Using your web browser, visit /install/app.php/update in your board's root (e.g.
http://www.example.com/yourforum/install/app.php/update). You will see the following warning message: No valid update directory was found, please make sure you uploaded the relevant files. This is expected and not an error ... Select "Update database only" and click Submit"
At /update I see the this image
The notice "No valid update directory ...." and "Update database only" and "Submit" are not seen.
Only the single word "Update" it is a hot link.
Should I click it? Will that generate a link to "Update database only"?
