A page in the forum? Not sure what you mean.
Pages are created in Wordpress and not in wpForo or other plugins.
Or you didn't describe the issue correctly. Is the issue related to wpForo plugin?
It seems you're using the "Turn WordPress to wpForo" option. In this case, you should know that all WordPress page URLs should be inserted in the “Exclude Page URLs” textarea. Please read the information under that option and the documentation before using it: https://wpforo.com/docs/root/getting-started/forum-page/turn-wordpress-to-wpforo/
