errors after upgrading woocommerce 8.3

Thanks for the report. Do you happen to have the full stack trace of the deprecation notice? Should can probably find it in your php error logs.

this is the line 2538

/**
* Replaces the set group separator by another one
*
* @param string $part The string to sanitize.
* @return string Sanitized string.
*/
protected function sanitize_key_part( $part ) {
return str_replace( ‘:’, ‘-‘, $part );
}

thank you

Yes, we can identify that it’s the sanitize_key_part() function, but we’d like to know who’s calling it.

If you can take a look at your error logs you will find the full error trace that looks something like this and will tell us more about the issue:

Sadly that’s not the stack trace, they might be disabled on your server. We’ll fix this in an upcoming release.

Maybe this is more helpful ?

No, but we’ll release an update soon. This was fixed on GitHub already ??
