ok I tried to upload a new version of wordpress and got it all wrong. Almost lost everything... I have finally reverted back to an older version and it is mostly working other than I am locked out of my admin. this is the error message I have been getting.
Fatal error: Call to undefined function: is_multisite() in /homepages/14/d271388824/htdocs/webportfolio/blog/wp-admin/admin.php on line 43
what do I need to do?
here is my site if it helps... http://www.glazefolio.com/blog
