Snapshot Plug causing 500 Internal Server Error.

A few days ago our site went completely offline with a 500 Internal Server Error.

Once we noticed, we tried to restore the site from a back up. We got the site up and running only to be see the 500 Internal Server Error just a few minutes later.

We then contacted our hosting provider, they got the site back up, however, they reset all our plugins by deactivating them.

We then started the process of activating all the plugins one by one trying to catch the problematic plugin and we found the source of the problem to be WPMU Dev’s Snapshot Version 3.0.4.

Now another set of problems.

1) When trying to activate Snapshot we immediately received the dreaded “500 Internal Server Error” and the site goes down.

2) When trying to Delete Snapshot, the plug WONT delete, instead we get this error message:

Deletion failed: <!DOCTYPE HTML PUBLIC “-//IETF//DTD HTML 2.0//EN”> 500 Internal Server Error Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator and inform them of the time the error occurred, and the actions you performed just before this error. More information about this error may be available in the server error log.

Please help WPMU Super guys! (Thanks)

(I’ve attached 2 screenshots of the errors)

    Hey there Salespro Domains,

    hope you’re having a beautiful day and thanks for reaching us! :slight_smile:

    Could you please access your server through FTP, edit the wp-config.php file, find a line like

    define('WP_DEBUG', false);

    and replace it with the following (if the above line doesn’t exist, simply insert next snippet just above the /* That’s all, stop editing! Happy blogging. */ comment)

    // Enable WP_DEBUG mode
    define('WP_DEBUG', true);
    // Enable Debug logging to the /wp-content/debug.log file
    define('WP_DEBUG_LOG', true);
    // Disable display of errors and warnings
    define('WP_DEBUG_DISPLAY', false);
    @ini_set('display_errors', 0);

    Then go ahead and try to replicate the error by activating Snapshot plugin.

    By doing so, a /wp-content/debug.log file should be created.

    Simply download it, rename it to debug.txt and attach it here in your next reply.

    This should reveal to us what’s going on there, I look forward for your results!

    Warm regards,
