Invalid argument in line 12

Hi @epsupport,

Thank you very much for your swift reply. I’ve always admired your support!

1. I’m using the short code: [em_events]

2. The events were created by me. The import/export plugin was/is deactivated (but expected to be needed)


Additional information:
—
The auto-update of the plugin has been left active since 2023.
—
I created the website back in 2023, and installed the plugin at that time. No one has edited or touched the website since then (also didn’t add or delete any events). I just got the information that it seemed like there was a problem with the calendar-page, and when I went to the website, the plugin isn’t working.
—
– I’ve tried to simply changed the event dates to 2025 to see if the events would appear, but still the same error.

– I deleted and reinstalled the plugin, but still the same error.

– I tried to create a new event, and got the following error code (in the “date and time” tab):

Fatal error: Uncaught Exception: DateTime::__construct() [<a href=’http://php.net/manual/en/datetime.construct’>datetime.construct</a>%5D: Failed to parse time string (2025-09-17 6:i A) at position 11 (6): Unexpected character in /var/www/jensen-bugge.dk/public_html/wp-content/plugins/eventprime-event-calendar-management/includes/class-eventprime-functions.php:1768 Stack trace: #0 /var/www/jensen-bugge.dk/public_html/wp-content/plugins/eventprime-event-calendar-management/includes/class-eventprime-functions.php(1768): DateTime->__construct(‘2025-09-17 6:i …’) #1 /var/www/jensen-bugge.dk/public_html/wp-content/plugins/eventprime-event-calendar-management/includes/class-eventprime-functions.php(3602): Eventprime_Basic_Functions->ep_get_event_date_time_diff(Object(stdClass)) #2 /var/www/jensen-bugge.dk/public_html/wp-content/plugins/eventprime-event-calendar-management/admin/class-eventprime-event-calendar-management-admin.php(1370): Eventprime_Basic_Functions->get_single_event(1025, Object(WP_Post)) #3 /var/www/jensen-bugge in /var/www/jensen-bugge.dk/public_html/wp-content/plugins/eventprime-event-calendar-management/includes/class-eventprime-functions.php on line 1768

When trying to create a new event, the start and end time looks weird:

Please let me know, if you need full access to the backend.

Once again, thank you very much for your support!

I also got this email below, 4 hours ago from WordPress. Maybe that can also help pinpoint the problem:

WordPress has a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

In this case, WordPress caught an error with one of your plugins, EventPrime – Modern Events Calendar, Bookings and Tickets.

First, visit your website (https://jensen-bugge.dk/) and check for any visible issues. Next, visit the page where the error was caught (https://jensen-bugge.dk/wp-admin/post.php?post=1025&action=edit&message=6) and check for any visible issues.

Please contact your host for assistance with investigating this issue further.

If your site appears broken and you can't access your dashboard normally, WordPress now has a special "recovery mode". This lets you safely login to your dashboard and investigate further.

https://jensen-bugge.dk/wp-login.php?action=enter_recovery_mode&rm_token=TOKENREMOVED

To keep your site safe, this link will expire in 1 day. Don't worry about that, though: a new link will be emailed to you if the error occurs again after it expires.

When seeking help with this issue, you may be asked for some of the following information:
WordPress version 6.8.2
Active theme: Divi (version 4.27.4)
Current plugin: EventPrime – Modern Events Calendar, Bookings and Tickets (version 4.1.4.0)
PHP version 7.4.33

Hi @epsupport,

I’m not really understanding your answer, which doesn’t address the issues.

Can you please support me in fixing the problem with the plugin?

Once again, thank you for your time!!

Hi @epsupport !

I updated, and it seems to work! Thank you!!

Though, when I create a new event, I’m not able to chose the time – it just says “12:i A”.

Please see print screen on this link: https://jensen-bugge.dk/wp-content/uploads/2025/09/time-not-working.png

Only after having saved the new event (without adding the start time), and I go back to edit the newly created event, it lets me change the time… But that’s not optimal for my client..

Can you please help me??
