Server 500 Internal Error on Admin Panel Pages

  • Hello, I was using your plugin and loved it up until I was unable to make plugin changes, and was hitting a 500 Internal Server Error.

    First thing I did, is I did what wasn’t suggestable, and I deleted the core directory of W3 Cache, and it killed access to my updates, and some other core functionality.

    Next, I went through to hunt down some possible solutions on Google, and I saw that W3 Cache effects the .htaccess file, so I went through, I removed that. Then I followed this guide to make sure I did everything.:

    First, delete all cache and deactivate the W3 Total Cache plugin.
    Delete the W3 Total Cache plugin from the Wp-content/plugins folder.
    Remove this line from Wp-config file – (define(‘WP_CACHE’, true) )
    Delete advanced-cache.php, db.php, wp-total-cache-config.php, and delete the entire w3tc folder from the Wp-content folder.
    Check the . htaccess file; if you see any code added by W3 Total Cache, remove it.

    And I am still not able to see a majority of my Admin Dashboard, unable to update, install/update/manage plugins.

    I’ve also tried uploading fresh contents of the WP-Includes, WP-Content, and WP-Admin folders with the overwrite permission for newer or different versions.

    The rest of the site seems to be functional which is good, but unfortunately I am kind of stuck at this point, and getting ready to do a complete overhaul of the site.

    Something tells me that the caching of the database would be the culprit at this point.

    If you know of anything that I could be missing, please let me know.

    UPDATE:

    I checked the WP-Settings.php file, and saw some other lines in there 

    if ( WP_CACHE && apply_filters( 'enable_loading_advanced_cache_dropin', false ) ) {
	// For an advanced caching plugin to use. Uses a static drop-in because you would only want one.
	WP_DEBUG ? include( WP_CONTENT_DIR . '/cache.php' ) : @include( WP_CONTENT_DIR . '/cache.php' );

	// Re-initialize any hooks added manually by advanced-cache.php
	if ( $wp_filter ) {
		$wp_filter = WP_Hook::build_preinitialized_hooks( $wp_filter );
	}
}

    Which I removed. Back end is still where it was, but I wanted to share that I discovered this bit of code.

    Final Update:

    After a bunch of time spent on this, I ended up needing to go into PHPMyAdmin and deactivating all plugins manually, which fixed the issue.

    Sauce:

    I was able to narrow it down to a combo issue, where a few plugins were the culprits after the caching.

    I’ll be trying this plugin again later but for now ??
