Support » Plugin: All-in-One WP Migration » Internal Server 500 Error After 4.7.1 Update

  • Resolved ChuckC3


    My site was automatically updated to 4.7.1 on January 11th and it has been down ever since with an “Internal Server 500 Error”. I have tried deactivating all of my plugins as well as renaming the active theme and that has not resolved the problem. I am going to try to have my web hosting company restore the site from a recent backup to restore the site back to normal operation and I will have to turn off automatic updates to prevent the 4.7.1 update from being installed to avoid this problem.

    Is anyone else having this problem? Can you please advise what I can do to resolve this problem?

    I had the same thing happen to me…worked for 3 hours on it and even tried to migrate the site manually. I got the same error.

    Found out that the hosting company was very bad – slow, only allowed small chunks (only 150MB) to be uploaded, etc.). So my guess is that the uploaded files were corrupt due to the slow uploads.

    I had my client switch to another company – I use Namecheap, but Bluehost is also good too – and it worked super fast with no problems (they allow several GB for uploads). She was able to get her money back from the other hosting company.

    I was able to resolve my problem after completely rebuilding my site (Fortunately, I had a good backup). Here are the steps I went through:

    1. Completely wiped out the original installation and removed all files from the web site
    2. Did a clean installation of WordPress 4.7
    3. Installed the UpdraftPlus plugin that I use for backups
    4. Used UpdraftPlus to restore the site from the most recent backup
    5. Upgraded to WordPress 4.7.1 again

    I don’t know what went wrong the first time I did the upgrade to 4.7.1 because it worked the second time. I have turned off automatic upgrades so that I won’t get caught by surprise again like this – my site was completely dead for almost two days before I discovered that it was down.

    I use Interserver for hosting and I’m generally happy with them. I run my WordPress site on an IIS platform. Interserver has told me that I should be on Linux but I have another site that requires IIS and SQL Server.



    Oh man…what a chore! I’m glad that you have it sorted out and good reminders to not have things on automatic upgrades!

    I work with half a dozen hosts and Interserver is the absolute worst for WordPress. The shared servers don’t have the resources to handle a core update.

    There are two possible solutions:

    First, try accessing the site via FTP or File Manager and deleting or renaming any caching plugins. With W3 Total Cache, you’ll need to delete the db.php file in your wp-content directory as well.

    Or, second option, I had to enter PhpMyAdmin and update manually the db_version in wp_options ( with the version number from the latest wordpress download package (

    Good luck.
