[Urgent] WordPress: Upgraded to PHP 7.3. Nothing Working

  • Hello,

    I recently have upgraded my Ubuntu VPS with: apt-get upgrade, apt-get dist-upgrade, and apt autoremove which upgraded my php from 7.2 to 7.3. My WordPress website was working great until I upgraded my PHP to 7.3. It was then saying “Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request”. Then, when I tried ” a2dismod php7.2″, ” a2enmod php7.3 “, “systemctl restart apache2”, I get:
    This page isn’t working x.com is currently unable to handle this request. HTTP ERROR 500

    I tried:
    – The most likely issue is a corrupted .htaccess file. Log in to your site root using FTP and rename your .htaccess file to .htaccess_old
    . Try loading your site to see if this has solved your problem. If it works, make sure to visit Settings > Permalinks and reset your permalinks. This will generate a new .htaccess file for you.
    – Try deactivating all of your Plugins to see if it is a Plugin issue. If you are unable to access your WordPress Administration Screens, deactivate your Plugins via FTP by following these instructions.
    – Switch the Theme to the WordPress default Theme (e.g. Twenty Seventeen) to eliminate any Theme-related problems.
    – Increase the PHP Memory limit
    – Try re-uploading the wp-admin and wp-includes folders from a fresh install of WordPress.

    Furthermore, my PHP is working for sure. I tested to rename my “index.php” in /var/www/wordpress to “index.php.backup” and created a new index.php with:
    <?php phpinfo(); ?>
    It shows the normal PHP page with version etc…

    I do not know what to do. The three most recent backups are corrupted…

    Please help me :/

  • Go to the wp-config.php file and change WP_DEBUG to true and you’ll be able to see what the actual error message is. That should also be available in your servers log files. Once you find out what the actual problem is, you’ll be able to start torubleshooting properly.

    Hello,
    Thanks for the reply.

    I changed the Boolean value to true and went to wp-content directory. However, I do not find debug.log. Could not find it even with sudo locate debug.log. Do you have any idea?

    Thanks,

    Why are you going to the wp-content directory? What does that have to do with your error? Maybe your server isn’t set up to write errors there, you’d have ot answer that for yourself.

    What does the error message say on your home page? That’s where you’d check it. You need to look at the page that the error is actually happening on.
