i have installed the event espresso plugin and some addons.

When i test the plugin, i filled out the formular for register at the test event. After press the button “Proceed to Finalize Registration” the formular is empty.

I found an error in the source code:

<div id="espresso-notices"><div id="espresso-notices-error" class="espresso-notices error fade-away" style="display:none;"><p>An error has occurred:<br />Vorname ist erforderlich.<br/><span class="tiny-text">EE_SPCO_Reg_Step_Attendee_Information - _verify_critical_attendee_details_are_set_and_validate_email - 873</span></p><a class="close-espresso-notice hide-if-no-js">&times;</a></div></div>

I already deactivate all plugins exlude event espresso, event espresso addons, polylang and google xml sitemap. But there is still the error.

Following Versions are install:
Wordpress 4.2.2
Event Espresso 4.6.31.p
Event Espresso – Barcode Scanner (EE 4.6.0+) 1.0.3.p
Event Espresso – Events Table View Template (EE 4.4.9+) Version 1.3.3.p
Event Espresso – Grid View Template (EE 4.4.9+) Version 1.2.3.p
Event Espresso – Ticketing (EE4+) 1.0.3.p
Google XML Sitemaps 4.0.8
Polylang 1.7.5

Version of PHP: 5.4.40-1

I using Event Espresso Requirements and gets an Passed with warnings:

Recommended Apache Modules
Not Found!
Some recommended Apache modules appear to be missing from your installation. This may be because of your PHP configuration or because they have not been enabled in your Apache configuration. While this may not cause any obvious errors, some features may not work correctly. Please contact your webhost about activating additional Apache modules or upgrading Apache. View installed Apache modules.

Which are the Recommended Apache Modules?

Here is an URL to test the installation:

Hi there Michael, thanks for getting a head start on troubleshooting!

Are there any caching services in use by your web host? For example, do they have any built-in caching services?

Here is information on your second question.

Required Modules and Server Configurations:

The mod_rewrite module for Apache servers (if using pretty permalinks)
An SSL certificate (if using an on-site payment method)
PHP cURL module (most payment methods require this)
fsockopen support (some payment methods require this)

Hi Lorenzo,

thanks for your feedback.

We are using an own root-server and have not installed caching services. I installed the plugin cachify, but already deactivate it for the troubleshooting.

mod_rewrite is installed. The other modules are not needed, because we are working only with free tickets.

Hi Michael,

I checked your site and viewed source. The page is missing some calls to a few JavaScript files, which is more than likely causing the errors you are seeing. The JS files get added via the wp_footer() hook, which might be missing from your theme’s footer.php template.

You can fix this by adding the wp_footer(); function to your theme’s footer.php file. There’s more info about the wp_footer() function in the WordPress codex.

Allright…it seems i forgot it…shame on me 😀

I have an other question. I hope it will be ok, i use the same thread.

I can´t open the language file to modify with POEdit. I get an error: the file has broken or an wrong format. I download the german file from Event Espresso 4 language file repository. How can i edit it?
