Yesterday, looking into error_log file I’ve found this error:
[15-Oct-2019 08:23:34 UTC] PHP Fatal error: Uncaught Error: Undefined constant ‘CRYPTO_AEAD_XCHACHA20POLY1305_IETF_KEYBYTES’ in /home/xxxx/public_html/wp-includes/sodium_compat/lib/constants.php:22
Sodium compat cryptographic library has been added into WP since 5.2 version.
But I never seen this error… someone knows something about this issue?
Thanks for any help!
Regards
