I get this when I go to ticketing.

Fatal error: Method EventEspresso\modules\ticket_selector\TicketSelectorStandard::__toString() must not throw an exception, caught ArgumentCountError: Too few arguments to function tw_output_details_before_the_ts(), 1 passed in /home/gagensoc/public_html/new/new/website/wp-includes/class-wp-hook.php on line 286 and exactly 2 expected in /home/gagensoc/public_html/new/new/website/wp-content/plugins/event-espresso-core-reg/modules/ticket_selector/DisplayTicketSelector.php on line 0

here is the website page where WP Debug showing:

I didn’t happen over the Spring in 2019…

The error message indicates something to do with a “tw_output_details_before_the_ts” function, which isn’t a function provided in EE4 core. Can you find the code that has the tw_output_details_before_the_ts() function and post its contents here? It may be in a separate plugin installed on your site.

How/where would I look?

I believe this is the problem in the template Funtions (I added a while back):
//Output details just after the ticket selector, the function has the Event ID ($EVT_ID)
//and EE_Event object $event available for use.
function tw_output_details_before_the_ts( $EVT_ID, $event ) {
echo “<h3>Discounts Available.

add_action( ‘AHEE__ticket_selector_chart__template__before_ticket_selector’, ‘tw_output_details_before_the_ts’, 10, 2 );

It was the last line. Can this be altered for the newer version?

add_action( ‘AHEE__ticket_selector_chart__template__before_ticket_selector’, ‘tw_output_details_before_the_ts’, 10, 2 );

Actually I’m not sure how that code would have worked, ever. The AHEE__ticket_selector_chart__template__before_ticket_selector action hook passes one argument, and your code has two.

Here’s what you can do to fix:
function tw_output_details_before_the_ts( $EVT_ID, $event ) {
function tw_output_details_before_the_ts( $event ) {

then change
add_action( 'AHEE__ticket_selector_chart__template__before_ticket_selector', 'tw_output_details_before_the_ts', 10, 2 );
add_action( 'AHEE__ticket_selector_chart__template__before_ticket_selector', 'tw_output_details_before_the_ts', 10 );

That fixed everything I got from Github last year!
