File manager disappears on enabling proxy

SYSTEM INFORMATION

Seems like I have same issue as described here https://forum.virtualmin.com/t/file-manager-disappears-when-proxy-is-enabled-on-virtual-server/120136

When I activate Web Configuration → Edit Proxy Website → Proxying enabled (set to Yes), the File manager disappears for that site. Other sites are unaffected.

At the same time, “Apache Website enabled” in ON.

Any ideas what may be wrong and how to fix it?

I think that requires more info. like what are you attempting to enable? does that site have some conflicting .htaccess ?

As far as I know, “Apache Website enabled” option is necessary for the website to work. Here’s what Virtualmin says about this option: “The module can create any or all of the following services for a new domain: mail, name service, web service. If this option is set to Yes, a new VirtualHost configuration section will be added to the Apache configuration and a new website home directory will be created”.

By the way, I may reproduce the issue with other websites, where even .htaccess doesn’t exist. Also it’s not dependent on whether this site is apache-php, apache with plain html or nodejs (I’m using regular Virtualmin, non-Pro version).

As soon as I turn off apache proxying for the website, File manager reappears for this site.

thanks, I do not seem to have this option
but then, I do not use Apache and Nginx proxying appears to be handled differently (I just edit the site’s .conf file)
