Hi,
1. i am afraid not, at least not without some custom programming.
2. you can change it in wp-admin / Classifieds / Options / Core panel
3. to do that you can add the code below in your theme functions.php file
add_filter( "wp", "paying_members_only_init", 50 );
function paying_members_only_init() {
if( is_singular( 'advert' ) && !current_user_can( "read" ) ) {
remove_action( 'adverts_tpl_single_bottom', 'adverts_single_contact_information' );
remove_action( 'adverts_tpl_single_bottom', 'adext_contact_form' );
remove_action( 'adverts_tpl_single_bottom', 'adext_bp_send_private_message_button', 50 );
add_action( 'adverts_tpl_single_bottom', "paying_members_only", 5 );
}
}
function paying_members_only( $post_id ) {
$flash = array( "error" => array(), "info" => array(), "warn" => array() );
$flash["warn"][] = array(
"message" => __( "Only logged-in can contact sellers." ),
"icon" => "adverts-icon-block"
);
adverts_flash( $flash );
}
4. you mean to hide the search bar on the [adverts_list]? If so then you can do that by using the shortcode with search_bar=”disabled” param like this
[adverts_list search_bar="disabled"]
See the docs here https://wpadverts.com/doc/creating-ads-list-adverts_list/ for more details.
5. you can do that using the adverts_post_type filter, please see the snippet here for more details https://github.com/simpliko/wpadverts-snippets/blob/master/custom-slugs/custom-slugs.php
How to best install the snippet you can read here https://github.com/simpliko/wpadverts-snippets/ at the bottom of the page.
