[2025-04-23T20:01:05.131718+00:00] general.ERROR: DateMalformedStringException: DateTime::modify(): Failed to parse time string (+0 onetime) at position 9 (e): Double timezone specification in <omitted>/vendors/minphp/date/src/Date.php:140 Stack trace: #0 <omitted>/vendors/minphp/date/src/Date.php(140): DateTime->modify() #1 <omitted>/app/models/invoices.php(1857): Minphp\Date\Date->modify() #2 <omitted>/app/controllers/admin_clients.php(562): Invoices->createRenewalFromService() #3 <omitted>/app/controllers/admin_clients.php(318): AdminClients->updateServices() #4 <omitted>/vendors/minphp/bridge/src/Lib/Dispatcher.php(142): AdminClients->services() #5 <omitted>/index.php(21): Dispatcher::dispatch() #6 {main}

 

Line 140 of <omitted>/vendors/minphp/date/src/Date.php is:

$modified_date->modify($modifier);

 

According PHP 8.3 specs (https://www.php.net/manual/en/datetime.modify.php):

DateTime::modify() now throws DateMalformedStringException if an invalid string is passed. Previously, it returned false, and a warning was emitted. date_modify() has not been changed.

 

Relevant PHP settings:

cat /usr/local/php83/lib/php.ini | grep timezone
; Defines the default timezone used by the date functions
; https://php.net/date.timezone
date.timezone = "UTC"
