Using the Plugin behind a Reverse Proxy causes redirecting everybody to /

    We have a webshop under example.com where the WordPress system is installed on a different server and rendered under example.com/blog using a apache proxy_pass directive.

    Everything works well. But after installing w3-total-cache, all example.com/blog/* pages redirect to example.com/ – even wp-admin is no longer available.

    $ curl https://www.example.com/blog/ -I
    HTTP/2 301
    date: Thu, 05 Dec 2019 14:42:31 GMT
    server: Apache
    x-redirect-by: WordPress
    location: https://www.example.com/
    content-type: text/html; charset=UTF-8

    We even restored the .htaccess after module installation, but it did not help.

    Where is this redirect coming from?

    Hello @aleximi

    I a sorry about the issue you are having and I am happy to help!
    Can you please share what caching method are you using for Page Cache? Have you tried switching to Disk: Basic and see if the issue persists?

    Thanks Marko,
    I believe it happend directly after installing, but I am not sure because I did not install it on my own.
    The problem is a bit, that wp-admin also is not available and I moved the plugin folder away to get the site at least accessible again.

    Any other ideas to debug?

    @vmarko after installation all worked, the problem started after enabling the page cache and chose Caching Methode Disk: Enhanced

    Hello @aleximi

    Thank you for the information. Can you please switch do Disk: Basic, save all settings and purge the cache and see if the issue persists?

    Just have to figure out how to do this without Backend Access.

    Can you share some technical background, why it may not work with “advanced”?

    Hello @aleximi
    This can happen if you incompletely describe the case and changes the hostname completely.
    The wp_redirect may come from the PgCache_Plugin.php file due to the host mismatch. This can be fixed by adding your secondary host to mirrors in Performance>Page Cache>Aliases.
    Enable the Cache alias hostnames: and add the URL in Additional home URLs:
    I hope this helps!

    Thank you so much. Commenting out the wp_redirect() and exit() lines helped to gain access to the backend and edit the options. This solved it.

    Maybe this can be made more robust … I guess if somebody activates it in such as setup and wp-admin is no longer accessible it can cause problems.

    Have a nice weekend.
