Fatal Error on PHP upgrade
-
WordPress keeps telling me to upgrade my PHP. Currently running 7.3.2. So I upgrade to 7.4 and suddenly I get an email telling me my site “is experiencing a technical issue”. The site itself seems to work fine, but the Dashboard is messed up. It shows the following error message:
Fatal error: Uncaught Error: Call to undefined function ctype_digit() in <root>/wp-content/plugins/jetpack/jetpack_vendor/automattic/jetpack-connection/legacy/class-jetpack-signature.php:218 Stack trace: #0 <root>/wp-content/plugins/jetpack/jetpack_vendor/automattic/jetpack-connection/src/class-client.php(184): Jetpack_Signature->sign_request('tC9MFJj9FFud$gX...', 1661127076, 't66nXwXJKc', '', 'GET', 'https://dashboa...', NULL, false) #1 <root>/wp-content/plugins/jetpack/jetpack_vendor/automattic/jetpack-connection/src/class-client.php(37): Automattic\Jetpack\Connection\Client::build_signed_request(Array, NULL) #2 <root>/wp-content/plugins/jetpack/modules/stats.php(1310): Automattic\Jetpack\Connection\Client::remote_request(Array) #3 <root>/wp-content/plugins/jetpack/jetpack_vendor/automattic/jetpack-connection/legacy/class-jetpack-signature.php on line 218
When I revert back to PHP 7.3.2 everything works fine again.
