Hi Rob,

Error 500 usually means a fatal error is being thrown on the request.

Do you have access to the servers error logs? (usually an error.log file or similar within the root directory of the site) If so take a look within that to see if you can see any errors from Event Espresso.

Another option is to enable WP_DEBUG on the site so that the full error message is display rather than just error 500, you can do that by setting define('WP_DEBUG', TRUE); in your wp-config.php file then repeating the above steps.

Or, use this snippet: https://gist.github.com/Pebblo/8787f5530ea777c84aaf62f075e55b32

That tells WP to not show the errors, but log them within a debug.log file on the server, once we have the error being thrown we can investigate this further.

Updating PHP should not cause the above.

Your site is running out of memory, it currently has 128MB available but apparently needs more. Try adding:

define( 'WP_MEMORY_LIMIT', '256M' );

To your wp-config.php file, it’s a little high but depends on your plugins and traffic so you may well just need a little more memory.

[06-Jan-2017 10:04:03 UTC] PHP Deprecated: Automatically populating $HTTP_RAW_POST_DATA is deprecated and will be removed in a future version. To avoid this warning set ‘always_populate_raw_post_data’ to ‘-1’ in php.ini and use the php://input stream instead. in Unknown on line 0

Hmm I did a quick search on this and it seems to be an issue with PHP 5.6, for example take a look here:

https://github.com/piwik/piwik/issues/6465

The ‘fix’ is to find always_populate_raw_post_data within your servers php.ini file and set it to -1.

[06-Jan-2017 10:06:29 UTC] PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 2013709 bytes) in /home/greenhil/public_html/wp-includes/functions.php on line 435

Same issue with memory, you’ll find that if your site is running out of memory that error will pop up in all kinds of places. If it consistently happens on a specific function then it could be that function has an issue (or again another symptom as the function may just require more memory than you have available, it depends).

My pleasure 🙂

Something else that may help is to update to PHP7, you may (likely) notice a big difference in speed if you update but again it depends if all of your plugins support it.
