Hello all! Apologies if this is a dumb question, I opened my Wiki last night so I'm still trying to figure stuff out
I've been running an OC Wiki on Fandom for years, but I'm currently migrating it to Miraheze because yeah. Fandom.
But I'm kind of struggling with the custom Infobox templates I have on my original wiki since they just don't seem to work on Miraheze and I can't figure out what I'm doing wrong :S
This is the template I'm trying to use (Ignore the documentation, I never bothered to update it)
https://drimare.fandom.com/wiki/Template:Infobox_character
But when I try to add it to Miraheze, it just becomes an HTML mess that looks like this
https://drimare.miraheze.org/wiki/Template:Infobox_character
I'm not sure what is going on here, or if maybe the Fandom infoboxes are formatted differently?? What would be the best approach here?
Thank you in advance!
