I am working on a new forum. I have many mods installed. Among them is Pretty URLs. I cannot access the template for that mod. And, today, I tried changing the "Pretty URLs" name under boards. Now I cannot access the page at all. The url in the browser does not reference the page. And there is no entry for either the new or the old name in the database.
If you believe it to be a Pretty URLs issue, why not post in the support topic for that mod?
I do not know where the support topic is.
