No left/right/center blocks show at all!

Oh dear, yes it's a custom SMF theme I'll just see what I can do with another theme before I give up and post a link

Do this, set your forum to the SMF Core Default theme.

Get all the articles/blocks issues resolved and then go back to installing your custom themes. Uninstall all SMF versions first.
Make sure to get the correct theme by looking for TP at the end of the theme name on the download page, most download pages will have two links with the 'Download' button being the SMF version and down below that the TP version.

Thanks very much for your help, everything works fine on the Core Default theme, now to find a new and suitable one!

Glad it worked.
