PHP 7 Compatibility

Hi Event Espresso,

Now that PHP 7 is official, I thought I’d give it a go to see if the performance improvements are as dramatic as rumored.

I activated PHP 7.02 on my server, but I get the below fatal error:
(I have replaced sensitive data with [removed])

Fatal error: Uncaught Error: Call to a member function init_caps() on null in [removed]plugins/event-espresso-core-reg/core/EE_System.core.php:181 Stack trace: #0 [removed]wp-includes/plugin.php(525): EE_System->load_espresso_addons(”) #1 /[removed]wp-content/plugins/event-espresso-core-reg/core/EE_Bootstrap.core.php(140): do_action(‘AHEE__EE_Bootst…’) #2 [removed]wp-includes/plugin.php(525): EE_Bootstrap::load_espresso_addons(”) #3 [removed]wp-settings.php(276): do_action(‘plugins_loaded’) #4 [removed]wp-config.php(87): require_once(‘[removed]…’) #5 [removed]wp-load.php(37): require_once(‘[removed]…’) #6 [removed]wp-admin/admin.php(31): require_once(‘[removed]…’) #7 [removed]wp-admin/index.php(10): require_once(‘[removed]…’) #8 in [removed]wp-content/plugins/event-espresso-core-reg/core/EE_System.core.php on line 181

I have since downgraded back to PHP 5.6 and it all works again.
Any ideas how to resolved this fatal error on PHP7, as I’m keen to test out the reputed performance improvements

Hi Chris,

Event Espresso 4 has not been tested with PHP 7 or HHVM at this time. For now, please continue to use a prior version of PHP.

Hi Lorenzo,

Thanks for the quick response.
I hope that this will be resolved quickly.

In the meantime, it might be worth revising the requirements page on your website, as it simply says 5.3.9+ which before Php 7 came out of beta wasn’t a problem but now it’s official some disappointment might occur amongst your potential new customers.

Kind Regards,

Thanks Chris. We saw another report come through this morning so I’ve updated the ticket for this issue and updated our requirements page with a note below the table.
