Not all hardware shows up when accessing Domoticz through Apache

[Timmiej93]

I know this question is probably more related to Apache than it is to Domoticz, but it's also Domoticz-specific, since the issues only arrize with Domoticz.

My Domoticz instance is available on the web, through a certain domain, together with some other webpages I host locally. All are available only to me. Let's refer to this access method as Domoticz Web, and accessing it locally through IP:port as Domoticz LAN.

I have noticed before that on Domoticz Web, I don't have access to all my Hardware. If I go to the hardware page on Domoticz Web, I get 6 hardware devices. If I go to the hardware page on Domoticz LAN, I get 9 hardware devices. This doesn't seem to be caused by specific hardware, since any new hardware I add shows up on Domoticz LAN, but not on Domoticz Web, so it seems to be an issue in the number of devices, not which devices they are. So far that has been manageable, since I hardly ever need to mess with the hardware devices.

However, a few days ago I changed the theme for Domoticz to machinon. On Domoticz LAN, everything works perfectly fine, but on Domoticz Web, I still get my previous theme. I tried clearing my browser's cache and app cache, but nothing changes. Same goes for incognito mode or a different browser, I still get my previous theme on Domoticz Web, and the new one on Domoticz LAN. When I go into the settings on Domoticz Web, it does (of course) show the theme to be set to machinon, but
Ignore this, before posting I decided to go ahead and apply the settings on Domoticz Web, without changing anything, and that actually changed the theme. So strange...

I'm still curious if anyone knows why not all of my hardware shows up on Domoticz Web though. Any ideas?
