More about this problem:
In a page I pasted the shortcode [bbp-forum-index]. This shows the forums that are available. The url of one forum is for example:
That url is not correct. All urls that are generated are not correct.
I changed the permalinks to standard. That gives for example a url as:
Can someone give me the correct url to a forum in my site so that I can try if it’s a problem of bbPress or my theme (Hybrid)?
http://www.stichtinginspiratiekring.nl/forums/forum/ledeninformatie/ is not correct, but which is?
Yesterday I stated a question on themehybrid.com, the payed forum of Justin Tadlock. He responded within 6 hours. He seems to care.
Why does no one of the bbPress team seems to care that because of an upgrade people are in trouble (or in my case their clients). No response, no possibility to contact anyone of bbPress. Please make bbPress a payed plugin and start providing decent support!
