adding blog & theme to newly set up network?

Thanks you for your reply, and forgive my vagueness! Starting out with this and a bit overwhelmed – have spent hours trying to resolve it and pleased that – with the help of you and others on the forums – I have created a network but now hope to reinstate the WP theme and files for original WP single site that I created.

To recap – created a single site – then tried to install network site on the same installation – using MAMP, local host. This backfired on me – whereby I couldn’t see my original blog page – sorry it was over a week ago (I did post on the forum about it – unsure how to add link to it, sorry) the error messages were as below:
When I tried to preview my current blog = ‘not found on the server’ or when I clicked on it in the dashboard an error message saying ‘Firefox has detected that the server is redirecting the request for this address in a way that will never complete.’

This plus MAMP problems meant that I finally uninstalled all and reinstalled all again, but not before saving the
HTDDOC’s folder (containging all the WP files for this blog) – and backed-up (exported) the database (could this be a zipped HTDOC’s folder by the way??) to my computer.

So now I have created network and installed a new WP (again with the invaluable guidance of other posts on this forum) and would like to somehow install my single site settings/WP files so that I can ressurect that blog as a sub-domain site and create another blog in the ‘primary site’.

I did try installing the saved WP files into the new install’s HTDOC’s folder originally – this does not seem to have resolved much, though the themes I saved in the original site are availble on this new mult-site/network – though as yet not my much modified (and cherished!)) blog. Unless I’m looking in the wrong place/ not doing something simple I could do to retrieve the modified files and upload the single site to the network…

The original Database will of been lost when I uninstalled MAMP I guess? I’ve checked on MAMP, PHPMyAdmin – the new Database is there – with 26 files – 9 of which have the pre-fix Wp_2 – the remaining 17 are just Wp files. If that casts any light???

Sorry this is such a long explanation – with perhaps not enough technical information…
I really hope it helps you understand where I”m at.

Lastly – I am in a quandry about sites and domains and getting that all going at the moment too. Getting an error message when I try and access 2nd site page (that I thought I’d created – but actually it’s not showing up in the Network Dasboard – just that I have one site and one user)
Error message: The requested URL /janursamajor was not found on this server.
Apache/2.0.64 (Unix) PHP/5.3.5 DAV/2 Server at localhost Port 80
2

So as not to confuse, think I’d better leave that question for a new post though, and concentrate on the question of the current post.

Thank you – please bear with me re: not enough for technical info and feel free to ask for more!

I did back it up – several times as I tried to make a child theme and so on.. but am uncertain where it is/how to re-instate it into the PHPMyAdmin.

Thanks for the link – I’ve just seen the Link button would of helped me there too!

Thank you – do you mean it remains in PHPmyadmin – or is exported to my hard-drive….?

I’ve made a few attempts to import the zipped HTDocs folder from my desktop that I thought was the export, into the phpmyadmin – having created a new data-base – it doesn’t seem to be successful!

Yes I did export it to a file, followed the WP instructions on how to back up to do so and just allowed the backup file name template to be used – the (stupid) thing is I do not recall what the file was called – have looked at the SQL database instructions to back-up and try and remind myself – see that the post fix seems to be _db_ So have done a search on my hard-drive for files with _db_ – and there are lots of files that come up, but none with that post fix per se…!

I just recall having an option to save an export as a zipped file – which is why I’ve got this zipped HTDocs folder on my desktop.

Sorry about the lack of clarity here – on a steep learning curve.
