php 8 not completely supported

ProfilePress uses an outdated version of pelago/emogrifier which is not PHP 8 compatible.

File: ProfilePressVendor\Pelago\Emogrifier
Function: handleXpathQueryWarnings
Line: 1463 – 1469

With PHP 8 the 5th parameter for callbacks of set_error_handler is omitted. It must be optional.

wrong:

public function handleXpathQueryWarnings(
    // phpcs:ignore Generic.CodeAnalysis.UnusedFunctionParameter
    $type,
    $message,
    $file,
    $line,
    array $context
)

correct:

public function handleXpathQueryWarnings(
    // phpcs:ignore Generic.CodeAnalysis.UnusedFunctionParameter
    $type,
    $message,
    $file,
    $line,
    array $context = []
)

This is only a fix. It would be better to use the newest version of pelago/emogrifier which out-of-the-box support PHP 8

With kind regards
