Fatal error: Call to undefined function after WP update

    Hi,

    This is the site I’m having an issue with http://interactivemediainstitute.com/cypsy22

    I just updated my version of wordpress to the latest update (from the previous update – so not a big jump). I now get this error.

    Fatal error: Call to undefined function get_user_locale() in /home/mediainstitute/public_html/cypsy22/wp-admin/admin-header.php on line 165

    I can see the site frontend fine. But this error is all I get for the admin side.

    I have followed as many of the steps in the (read this first) forum post. Emptied caches, all plugins are deactivated, etc. Still no joy. Need to get an update up on the site asap too!

    I’m also not super technical – I can do a certain amount – but some of the advice I’ve seen just doesn’t mean anything to me.

    The hosting company is Go Daddy and it’s Economy Linux Hosting with cPanel Renewal. Any other info that you need I’ll see if I can get – but I don’t know what’s needed!

    Since you have already tried manually resetting your plugins I would access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue (theme functions can interfere like plugins).

    If that still doesn’t work, you could try manually reinstalling WordPress and see if that makes a difference.

    Thanks.

    If I do that and it is a problem with the theme – what then? I’m reluctant to screw up the front end of the site – it’s a particularly active time for people looking at this site – it’s for a conference.

    Thanks!

    Also – I have a theme installed – Sparkling, but also have a child theme. Do I need to get rid of both?

    Thanks.

    You don’t need to get rid of the theme, you just need to narrow down where the issue is coming from. That’s what Geoffrey was giving advice for.

    Ok – I tried renaming the theme folder – just the parent, and then both. I still couldn’t access the backend admin area.

    My site also didn’t force itself back to the default theme – I just got this error:
    The parent theme is missing. Please install the “sparkling” parent theme.
    The same when the child theme was missing.

    Ok – I tried to manually reinstall wordpress – and now I just have a plain white screen on the admin end with no error message.

    That often means you have a 500 error (internal server error). These errors are often caused by plugin or theme function conflicts, I would try manually resetting your plugins (no Dashboard access required) again. If that resolves the issue, reactivate each one individually until you find the cause.

    If that does not resolve the issue, try switching to the default theme for your version of WordPress to rule-out a theme-specific issue. If you don’t have access to your admin panel, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue.

    If that does not resolve the issue, it’s possible that a .htaccess rule could be the source of the problem. To check for this, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, and rename the .htaccess file. If you can’t find a .htaccess file, make sure that you have set your SFTP or FTP client to view invisible files.

    If you weren’t able to resolve the issue by either resetting your plugins and theme or renaming your .htaccess file, we may be able to help, but we’ll need a more detailed error message. Internal server errors are usually described in more detail in the server error log. If you have access to your server error log, generate the error again, note the date and time, then immediately check your server error log for any errors that occurred during that time period. If you don’t have access to your server error log, ask your hosting provider to look for you.

    Thank you so much for all the detailed advice. I’ve gone through it all now with no success.

    I manually reset my plugins – to no effect. Still a blank screen on the admin end.

    I renamed the theme folders (adult and child) and that also didn’t work. Stilla white screen on the backend, as well as a white screen on the front end (it seems the default theme did not kick in).

    I tried renaming the htaccess file too – no joy unfortunately.

    I accessed what I think are the error logs – my cpanel is laid out a bit differently to how godaddy explains – but I think it’s right! There was just one error in there for today – and it’s pasted below. Does it help?

    Thanks again – I really appreciate the help!

    Hi again,
    If there is any chance of getting some more help to fix this problem I would be so grateful.

    I tried all the options suggested with no joy.

    The error message that I got is below. Is there anything that can be done to fix this? Or alternatively. Is there any way that I can even manage the content on the page without access to admin in the meantime? Just to add some text. It really is important that I can do it soon.
