Hey gang,

I’m working on a local copy of a client site. She was using 3.1.21.P, upgraded to 3.1.27.P. In testing it, the following error appears on the event registration page for events.

> Warning: Missing argument 2 for event_espresso_price_dropdown(),
> called in
> C:xampphtdocsbytheglasswp-contentuploadsespressotemplatesregistration_page_display.php

> on line 195
> Warning: extract() expects parameter 1 to be array, null given in
> C:xampphtdocsbytheglasswp-contentpluginsevent-espressoincludesfunctionspricing.php
> on line 200

Did I miss a step in the upgrade? Any ideas?

Yes, you need to update the template files located in \bytheglass\wp-content\uploads\espresso\templates\ . I usually use a recommend using a program called Diffmerge to compare the original template files to the ones in the espresso/templates folder.

I had the same problem but there are multiple differences between the template files, how do I know which changes to merge?

Hi there,

When in doubt, you can start with fresh templates from the newer version. If you have made modifications to the earlier version’s templates, you can copy the modifications into the newer version’s templates. When you’re finished, you can copy the modified files into /wp-content/uploads/espresso/templates.

If you haven’t made any customizations, and you’re simply trying to update to the new version of Event Espresso, you can remove the templates from /wp-content/uploads/espresso/templates using FTP or your host’s control panel file manager.

Please see this article in the documentation for more info:
