Before this, my board is working great with phpbbSEO. Once I have installed a new theme, prosilver, the problem occurs. Let me explain the issue briefly.
In the viewforum.php page, there is a post reply button. The link suppose to be http://www.domain.com/posting.php?mode=reply&f=3&t=1086
, but with this theme, it becomes this, http://www.domain.com/general-chat/
posting.php?mode=reply&f=3&t=1086. As a result, I receive 404 error page.
The error also occurs for forum icons and all miscellaneous images in that page. Can anyone help me?
