Fatal Error when using Front End Submission Forms

Hello

When you use Relevannsi and a Front End Submission Tool like CRED, you will receive a Fatal Error.

To replicate, you need to use as example Views and types, index a Custom Field with Relevanssi and use an Edit Form to submit a related post.

The Error is visible on submission.

It’s due to the fact that in indexing.php you added a Patch for ACF, that does not include wp-admin/includes/plugin.php.
(line 733)

If you add this below to your code, just above if (! is_plugin_active('advanced-custom-fields/acf.php')) return ; you will fix the issue:
include_once( ABSPATH . 'wp-admin/includes/plugin.php' );

This is also explained in the Codex:

Please let us know if we are wrong, but As Far I saw, this fixes the problem.
