ankitispace, check the search slug under settings>forums. Change that to something other than “search” and the search *should* work again with the prefix box unchecked.
I also have the same problem.
If I uncheck that Forum Prefix box, search doesn’t work.
This can’t be just me and person above… how is this fixed??
As soon as I renamed the post_name for the hardware image from “hardware” to “hardware-attachment” in wp_posts, I was able to use “hardware” as the forum slug in bbpress.
I found a filter that automatically adds “-attachment” to file slugs, so that file pages don’t automatically reserve slugs.
Really silly that it can happen though.
Was due to an image upload with hardware as the file name. Doesn’t seem right that bbpress doesn’t have its own “namespace” or taxonomy (sorry not wp pro here). Or am I just missing something?
