If it helps, I'm using Miraheze as my host of choice. As you can see from the above, it says Template: Template other despite the fact the page source begins with:
{{Infobox
|image = [[File:4004small.png]]
<!-- snip -->
The '''4004''', released in 1971, is the first microprocessor developed by Intel, and is regarded as the first...
Nowhere in the source is "Template other" mentioned, the only other templates I use are {{PAGENAME}} and {| for a table. How should I get rid of that red text at the top?

I note that there should be a rendered [[template:infobox]] on this preview, which is (apparently, it may well have been snipped from the right-hand side of the image) missing. I believe [[Template:other]] is called by [[template:infobox]] or another template that has been snipped off the code (which may well not be a minimal working example) and because it is missing—i.e. probably because the infobox page was imported (probably from Wikipedia or another wiki with complex multi-level templates) without the various other required templates it calls up—, it ends up throwing this onto the page.
