server error 500 w. 4.4 upgrade /tried deactivate plugin

    Hello,
    Very much a novice, but had great use of this forum before. I just can’t find a solution for this issue – I had the option of updating to the new version, and I usually just trust the dashboard and go for the recommended upgrades. I pressed upgrade for the 4.4 and waited, then scrolled down to see there were plugin upgrades as well, which I marked for upgrading too.

    Here’s where it went wrong. Somewhere between pressing upgrade, waiting a little, and refreshing, I got a “Server error 500 – The website encountered an error while retrieving http://www.shitsandgiggles.dk/wp-admin/. It may be down for maintenance or configured incorrectly.”

    I read that deactivating all plugins might help, so I found my way to phpMyAdmin and did this but nothing changed.

    Also, now I can’t find the option_name column or the active_plugins, which I assume have been deactivated then.

    I have no idea what to do. I don’t know if it just takes some time or if I messed up somewhere. I’m using one.com if that’s a useful information. Any step-by-step would be greatly appreciated!

    – Please check the error logs on your server for a more specific error message and see why it’s failing. If you need help locating them, ask your hosting provider to help you with that.
    – If you cannot find error logs or if you don’t find any helpful info in the error logs, try Enabling debugging and post the results.

    Hi Tara!
    I believe we’ve managed to debug. Let me know what you think –

    The error is showing as:
    Fatal error: Class ‘WP_Widget’ not found in /customers/6/d/9/shitsandgiggles.dk/httpd.www/wp-includes/widgets/class-wp-widget-pages.php on line 17

    In file manager on the c panel
    Line 17 on that file is:
    class WP_Widget_Pages extends WP_Widget {

    Try:

    – deactivating ALL (yes all) plugins temporarily to see if this resolves the problem (plugin functions can interfere). If this works, 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. Sometimes, an apparently inactive plugin can still cause problems. Also remember to deactivate any plugins in the mu-plugins folder (if you have created such folder). The easiest way is to rename that folder to mu-plugins-old.
    – switching to the unedited default Theme (Twenty Sixteen, etc.) for a moment using the WP dashboard to rule out any theme-specific issue (theme functions can interfere like plugins). If you don’t have access to your admin area, use FTP , or your web-host’s cPanel or whatever file management application your host provides. Navigate to /wp-content/themes/ and switch to the default theme by renaming your current theme’s folder by adding “-old” to the end of the folder name. Alternately, you can remove other themes except the default theme. That will force your site to use it.
    – If all the above steps do not resolve the issue, then try MANUALLY updating. Download a fresh copy of the WordPress .zip file to your computer, unzip it, and use that to copy up all files and folders EXCEPT the wp-config.php file and the /wp-content/ directory. You may need to delete the old wp-admin and wp-includes folders and files on your server before uploading the new ones. Read the Manual Update directions first.
