Errors After Pro Theme Update

Hi, After the Pro theme update I’m getting the following errors and one of our plugins isn’t working now. I’ve checked for space before the opening php tag. Do you have any idea how to fix it? Thanks.

Hello, good day. What are the filters or action names you are connecting to? Are you redirecting in this plugin? You might need to flush the ob_buffer. Or change your PHP settings to allow modifying the headers after data is sent.

This is a third-party plugin that we’ve had for about 5 years and there haven’t been problems so I don’t know about filters or action names. How do I flush the ob_buffer or change the PHP settings like you suggest?

Also, is there a way to rollback the theme easily?

Thanks.

Here is the broken page if that helps: https://www.tektonministries.org/tekton-registration-form/?pilgrimage=31419

I have answered your other topic on rolling back the theme. Let me know if you have any questions.

That’s the .ini flag for output buffering, that might solve it.
php_flag output_buffering on

Depending on the amount of work for upgrading this plugin. I recommend you look into our One product.
