Many problems occur when you haven't configured a git repository. Do it.

Wrong names shown in recent changes!

If you have non-ASCII characters look like \012\305 or something, run this command:

git config core.quotepath false

Can't rename hyphae with some names!

It's a known bug. For the time being, administrators of wikis can move the hyphae manually from the server.

I've added a hypha outside of Mycorrhiza but it's not displayed on the wiki!

Mycorrhiza cannot keep track of everything you do on your computer. Visit /reindex and the engine will reindex all hyphae, including the one you've added. The reindexation happens quickly.
