Hello,

I suddenly started to see the following error message in the EE4 table view:

Warning: array_shift() expects parameter 1 to be array, string given in /home/clients/1d989383ee11099bb2d8468c003d5c0c/web/wp-content/uploads/espresso/templates/template.oa.php on line 132

You can see the error here: https://www.genevaphotoclub.com/dates-prices/

Could you help?

Here is the code on template.oa.php:

Line 132:
$ticket = array_shift( $tickets );

Full code:
