I don't doubt you at all and thanks for the offer; I may have to take you up on that.

Interesting development today:

The first problem was

'Warning backend already exists.'

Now, after changing the

/config.php.bkp

To:

/config.php

I get this. . .

'Warning frontend already exists.'

All this is a direct result of a fresh upload, changing the

/config.php.bkp

To:

/config.php

Then navigating to the install folder, opening the first page where it asks for customer number and enter install.

So all in all, we have gone from the backend existing to now front end existing but site still not existing....:D

It certainly makes for a more interesting experience.
Could you send me a link for ticket support please?

Make sure you're actually going to /core/install/install.php rather than just refreshing the page. As refreshing the page will simply reload makeconfig.php. You need to start from scratch at /core/install/install.php. As long as you have both config files renamed and the core config file populated with valid database credentials you should get straight to the install process.

If you need to raise a ticket go here:

You'll need to request that the ticket is sent to me.

I have tried it in 3 different browsers and always ended up in the same position. . .

Before I go for the ticket option, is there anyway to skip the auto configuration page?
I would like to try the config edits manually just as before..

Ta. . .

If you do the config edits correctly, that does skip the makeconfig page.

Mmmmn. That would explain why I didn't see it with 5.1.10 the first time.
Ultra bamboozled now. . .

However, I will persist a little further.

Thanks again...

But still doesn't explain the frontend/backend conundrum.
