  • I was in the process of updating WordPress when it froze and would not continue. Now when I try to log into my blog I get this message:

    Fatal error: Call to undefined function is_multisite() in /home/content/s/s/h/ssharick/html/wp-includes/wp-db.php on line 505

    Blog address is

    Any suggestions?

    Thank you

    – switching to the default theme by renaming your current theme’s folder using FTP or whatever file management application your host provides.

    resetting the plugins folder by FTP or phpMyAdmin.

    – re-running the upgrade manually.

    No this doesn’t seem to work. After following the two steps I still cannot get into my site without getting the same error.

    Did you try re-running the upgrade manually?

    I have gotten this same error message several times. I have done everything stated on this forum, even have broghten in an expert who is a programmer who develops WP sites. We get it up and running and a few days later we get the same message.

    This is getting beyond frustrating now, why is this happening? I do not want to go through the efforts of uploading alot of content and then end up getting this same 505 error message.

    I don’t feel this new upgrade to 3.0 is working properly because before I upgraded I was fine.

    What can I do to prevent this constant error message?
