Hi there,
A WP update today broke our site, but the error is resolved when we deactivate Event Espresso. The errors are:

Warning: session_start(): Cannot send session cache limiter – headers already sent (output started at /home/hshv6425/public_html/wp-content/themes/ultimatum/wonderfoundry/helpers/wonderworkshelper.php:1) in /home/hshv6425/public_html/wp-content/plugins/event-espresso-core-reg/core/services/session/SessionStartHandler.php on line 65

Warning: Cannot modify header information – headers already sent by (output started at /home/hshv6425/public_html/wp-content/themes/ultimatum/wonderfoundry/helpers/wonderworkshelper.php:1) in /home/hshv6425/public_html/wp-includes/pluggable.php on line 1265

Thank you for your help!

Hi there,

Although Event Espresso is shown in the error above, the cause is actually from your site’s theme.

The error shows EE is trying to start a session, but something has already been sent to the browser when it shouldn’t have been, that’s what this part is:

headers already sent by (output started at /home/hshv6425/public_html/wp-content/themes/ultimatum/wonderfoundry/helpers/wonderworkshelper.php:1)

Line 1 of wonderworkshelper.php file in your theme is outputting something to browser, often a leading space.

Can you send me a copy of the theme so I can take a look?
