looks like misc.php file is missing or it is not accessible.
run file verification tool from below location. what does it report ?
forum admin panel >> tools & maintenance >> file verification
ignore reported images & ignore files reported from install folder & its sub-folders
ignore above response. there is something wrong with configuration.
two instances of forum page are loading for misc.php file actions
first instance is getting 404 error & second one with the content
