Maybe this will help someone else who is having problems with forum pagination not working right and/or replies that don’t seem to show up…

A client was reporting that some forum replies were taking hours to a day or more to appear in some topics on the website. I was able to confirm this by mirroring the site to my localhost; I could see the replies in the administrative section but they weren’t showing up on the front end of the site, and would only show up if I posted a bunch of additional replies to trigger a new page. It only happened on topics that reached the point of needing additional pages, and whatever value I set for replies-per-page in the settings had no effect. After debugging the BBPress query object, I noticed that the “posts_per_page” values were different from the settings I had configured for BBPress.

I did a site-wide file search for the string “posts_per_page” and saw that the theme (Salient from Themeforest) had a function in functions.php that had added a filter for “pre_get_posts” and was hardcoding the “posts_per_page” variable to 12, which is the value I saw when dumping the BBPress query object. Once I set the BBPress replies-per-page setting to that value (12), pagination seemed to work and posts were showing up.

Anyway… maybe this will help someone else with the same issue with their debugging.

Thanks for sharing , if you havent already contact the theme author so that it wont happen to future users of both bbPress and the Salient theme.

i can not thank you enough for your answer it is a major bug in salient theme which leads pagination not working even if value is set via admin setting.

Thank’s a lot.
