Moved site, admin broken

hav you tried:

-deactivating ALL plugins (yes, all) temporarily to narrow down the problem. If the problem goes away, re-activate them individually (one-by-one) to find the problematic plugin(s). If you can’t get into your admin dashboard, try resetting the plugins folder by FTP or phpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems (because the hooks remain unless plugins completely removed or some plugins stick around in cached files. So by renaming the folder, you break them and force them inactive).

-switching to the unedited default theme (Twenty Eleven) for a moment using the WP dashboard. If you don’t have access to your admin area, you can switch to the default theme by renaming your current theme’s folder in wp-content/themes via FTP or SFTP or whatever file management application your host provides. The idea is to force WordPress to fall back to the default theme to rule out any theme-specific issue.

ok and if resetting all the plugins still doesn’t solve the problem, what are some other options?

Thanks t-p. One of these seemed to work, though I’m not sure which because although I did them in the order you said, my ftp client behaved like it was renaming more slowly than expected so I sort of did them both at the same time.

But it now works and I can use the admin. However, it has led to other problems.

1) It seems to have broken wp_head so I had to manually put some script links in (like jquery).

2) I can’t seem to logout, it just hangs.

Thanks again! You at least got it moving again.

you are welcome ??

This problematic WordPress install continues. Logging into wp-admin is impossible unless I temporarily change the name of the theme (customised Sandbox theme) as t-p suggested. The rest of the site works fine and admin works locally but now it is online, wp-admin throws up a blank page.

If I change the theme name, the rest of the site breaks, but I can access admin.

When I change the theme name back to what it was, I can access most of admin (and the rest of the site comes back), but I can’t logout of admin. I also cannot access admin from a different browser (I guess where the session is not logged).

Not sure how to troubleshoot from here.

The error given out on pages such as the failed logout page is:

Just to be clear, there is also an error on pages that do work normally which is:

Notice: get_settings is deprecated since version 2.1! Use get_option() instead. in /customers/5/0/0/yyy/httpd.www/xxx/wp-includes/functions.php on line 2628 Notice: wp_enqueue_script was called incorrectly.
