When testing our gateway with purchasing a ticket, we are receiving the following error: This registration step could not be completed. Please refresh the page and try again. This comes after a payment method is entered and submitted.

If we enable the PDF invoice payment method, we can successfully complete the purchase of a ticket. I have code from Chrome’s developer console that shows once the above error displays:

jquery.js:4 POST 500 (Internal Server Error)
send @ jquery.js:4
ajax @ jquery.js:4
submit_reg_form @ single_page_checkout.js:808
process_next_step @ single_page_checkout.js:754
(anonymous) @ single_page_checkout.js:411
dispatch @ jquery.js:3
r.handle @ jquery.js:3
That’s from Developer Tools console

We also attempted increasing the memory limit using define( “WP_MEMORY_LIMIT”, “100M”) in the wp-config.php file. The max_input_vars is set to 10000.

Lastly, we also are using PaidMembershipsPro with the gateway successfully.

The 500 error means there’s a fatal error happening during the ajax request. You may be able to capture that fatal error with WP_DEBUG_LOG. Here’s a link to the WordPress codex that shows how to log the errors without displaying them:

I have enabled debugging and this is the error I found in the log file:

[16-Oct-2017 16:18:03 UTC] PHP Fatal error: Call to undefined function EventEspresso\core\services\formatters\iconv() in /home/spiritof33/public_html/wp-content/plugins/event-espresso-core-reg/core/services/formatters/Windows1252.php on line 33

Thank you for your help. It is much appreciated.

Hi there,

Please update to the latest version of Event Espresso 4 (currently 4.9.48), we added a check for this in 4.9.39, as your site is currently using 4.9.38 you need to update to prevent the error.

OK the error is happening because the two following conditions were met:

1) Your server’s installation of PHP does not have the iconv() function enabled
2) Your site’s copy of Event Espresso is out of date. (EE4.9.38) Older versions of Event Espresso 4 attempted to use the iconv() function to convert the Event’s description characters before sending to Newer versions include a check to make sure iconv() is installed before attempting to use it.

The simplest solution in this case is update to the current version of Event Espresso 4 (currently Event Espresso 4.9.48.p).
