Issue with version 4.10.0

Since the update to version 4.10.0 I get the following message when activating other plugins while relevanssi plugin is activated:

“The plugin produced x characters with unexpected output during activation.”

When activating the other plugin while relevanssi plugin is deactivated no message is produced.

I tracked down the issue and isolated the root cause. This happens when a post is created during activation of the other plugin (e.g. Contact Form 7 creates a default form). In this case the function relevanssi_rankmath_noindex in file rankmath.php gets called and issues the following warning:

“in_array() expects parameter 2 to be array, string given”
