Exclude Multiple Custom Post Types

Try this:

if( !is_page( ) && 'first-type' != get_post_type() && 'second-type' != get_post_type() && file_exists( $fileName )){

or this:

if( !is_page( ) && !in_array(get_post_type(), array("first-type", "second-type")) && file_exists( $fileName )){

Thanks!

The first one worked ??

Im also interested on disabling the plugin on different categories or post types. Im using the ‘The Events Calendar’ plugin which creates posts for each new event, but I would like to exclude that category. Any help ?

There are instructions for excluding specific categories here: https://www.umbrellastudio.com/wordpress/bottom-of-every-post/
