bbPress.org

Hi,
I have the latest version of wordpress running (4.5.2) and latest version of bbPress.
Everything was working just fine before i moved my host from windows to Linux server.
Now i can see the forums and topics in each forum. but when i open a topic the content and replies are not shown in the pages, only the reply form shows up.
I can see the replies in the admin panel but clicking view from back end opens the front end reply to … without the reply content.

I have already tried these :
1) disabling all other plugins
2) switching to wordpress default themes
3) creating a new page with bbPress shortcode
4) copying the php code provided in other forums
5) removing and re-installing bbPress

it’s driving me crazy ! i have tried all 2 links on google’s 2 first pages for search results of “bbPress content not showing up”, “bbPress topic content not showing”, “bbPress replies not shown”,…

Best Regards,
Kaveh
