Azure Wordpress Site Returns 500 Errors After Plugin Update

Question

I have a Wordpress site which is hosted on Microsoft Azure, and the site is located at http://bitcoinpricelive.com

I recently updated a plugin called W3 Total Cache. After doing this the site was returning errors and going to wp-admin told me there was a problem with that plugin and i needed to delete: advanced-cache.php and object-cache.php

I deleted those two files but then the wp-admin page showed no information at all. I documented this aspect a bit more on Wordpress forums: https://wordpress.org/support/topic/w3-total-cache-error-after-updating-plugin/

Additionally, I tried googling for many fixes to this problem from modifying the .htaccess file to deleting W3 Total Cache components.

On the Azure side of things I get errors from source: W3SVC-WP, event id: 2289, and from source: W3SVC-WP, event id: 2284. I have been looking at documentation on the Microsoft site as well here: https://technet.microsoft.com/en-us/library/cc734951(v=ws.10).aspx

I can still login to the server via FileVilla and make changes if needed.

How can I debug this?

Answer 1

I would try to uninstall the extension via Azure's web portal, restart the app. Delete the extensions dir using SCM ( https://my_app_subdomain.scm.azurewebsites.net/DebugConsole ). Restart the app again. And maybe redeploy your app. It's possible the plugin messed with .htaaccess or something.

From Willian: Try delete the w3-cache directory in wp-content.
