White Screen (500 Error) when user picks ticket quantity and hits “Register”…
The error that comes up in my error logs is:
[24-Aug-2016 22:33:29] PHP Fatal error: Can’t inherit abstract function EventEspresso\core\services\commands\CommandHandlerInterface::handle() (previously declared abstract in EventEspresso\core\services\commands\CommandHandler) in /var/www/vhosts/removed.com/httpdocs/cpofnys/wp-content/plugins/event-espresso-core-reg/core/services/commands/CommandHandler.php on line 19
I am on CentOS5, running PHP5.3 (which I know is not ideal, would this cause it? it DID work for over 2 months until today!)
Thank you!

I should mention that I have disabled all other plugins and it didn’t work. I should also mention that although I am running PHP5.3 Event Espresso has been running flawlessly for over a month until recently (client informed me today).
Any help would be greatly appreciated.

Hi there,
What specific version number of PHP 5.3 are you using?
You can find this within Event Espresso -> Maintenance -> System information.
Search for ‘php_version’.

I’m running 5.3.5. I should mention that it has worked for weeks. I’m not sure when it stopped. I updated to the latest, but also rolled back to see if that helps, it didn’t. Why would it suddenly change?

Hey Lorenzo, thanks… The only email I got was the “quick start” which I already knew about and had installed the system. Did you have any updated on my issue? Thank you so much, you guys rock.

Hi Eric,
I’m sorry you’ve not received any response, Lorenzo replied via email shortly after posting the above, I’ll add the details here.
Basically this is caused by a PHP bug that was fixed in PHP 5.3.9 and above, you can view the details here:
https://bugs.php.net/bug.php?id=43200
and
http://stackoverflow.com/questions/17525620/php-fatal-error-cant-inherit-abstract-function
To fix this the version of PHP will need to be updated on the server, if you need to stick with 5.3 then I would highly recommend updating to the last release version which is 5.3.29
However if you can, you would be better updating to PHP 5.6 or above.
Is this VPS hosting or similar? As in can you issue a ticket with your hosting company to update/switch you to a newer version of PHP or would you need to do this yourself?
The version change that highlights this bug was made in 4.9.5, your site previously ran 4.9.1 which is why it worked before now. I can install 4.9.1 on your site to get your registrations up and running again for the time being if you would like?However moving forward PHP will need to be updated on the server in order to use the latest version of EE.

For future reference, where can I download older versions of EE? Just in case.
Thank you!!!!

I’ve actually installed EE4.9.4 so that you have all of the bugfixes up until the version that highlights this installed on your site.
Currently there are 2 versions of EE installed on your site (only one activated), v4.9.4 and the latest version. I’m assuming you didn’t make any changes to the current version and it can be deleted? I didn’t want to just remove it without checking first.
I ran a test registration to confirm and had no issues, can you confirm please?
You can download previous versions here.

You’re most welcome, Eric.
Just remember not to run the auto update when updating your plugins until PHP has been updated or you’ll end up back with the same problem 🙂
