I went into Permalink Settings, applied the code /%postname%/ to the Custom Structure field. Then, I get a message I need to update web.config and my site breaks.
Restoring the permalinks to default fixes my site.
I don't see any web.config file in the WordPress directory. What folder would it be under and what do I need to modify in it?
Why does my site not just update the links without this step? Thanks!
