Price Modifier Plugin Issues

Hi – I’ve been using Arpana’s Price Modifier plugin in order for my registrants to add things like meals to their registrations. The plugin itself is still working okay, but it causes issues in the backend such as when trying to preview or send test of the event emails. I get fatal WP errors when trying this. I have tried contacting Arpana but have not received a response in the past – it seems like they are no longer supporting this plugin. Are there other plugins or even some Event Espresso functionality we can use to allow registrants to add on meals or other items to their registrations?

Here is the error I receive when trying to preview an email message:

An error of type E_ERROR was caused in line 222 of the file /home1/oaregion/public_html/wp-content/plugins/eea-pricing/EE_Pricing.class.php. Error message: Uncaught Error: Call to a member function get() on null in /home1/oaregion/public_html/wp-content/plugins/eea-pricing/EE_Pricing.class.php:222
