How to increase the price limits

Go to the child theme folder > edit functions.php and add the following code:

add_filter( 'wpj_job_amount_max_limit_level_filter', 'wpj_change_price_settings_max_limits' ); 
add_filter( 'wpj_extra_amount_max_limit_level_filter', 'wpj_change_price_settings_max_limits' ); 
add_filter( 'wpj_custom_extra_amount_max_limit_level_filter', 'wpj_change_price_settings_max_limits' ); 
add_filter( 'wpj_job_amount_max_limit_subscription_filter', 'wpj_change_price_settings_max_limits' ); 
add_filter( 'wpj_extra_amount_max_limit_subscription_filter', 'wpj_change_price_settings_max_limits' ); 
add_filter( 'wpj_custom_extra_amount_max_limit_subscription_filter', 'wpj_change_price_settings_max_limits' ); 
add_filter( 'wpj_package_amount_max_limit_filter', 'wpj_change_price_settings_max_limits' ); 
add_filter( 'wpj_custom_offer_amount_max_limit_filter', 'wpj_change_price_settings_max_limits' ); 

function wpj_change_price_settings_max_limits( $limit ) { $limit = 10000; return $limit; }

Replace 10000 from the $limit variable with any other max value you want.
