Uncaught TypeError: strip_tags():

Replies: 0

Hello,

I installed a plugin on the web that found several problem files with Full scan, which I quarantined.

However, this morning I received an email regarding a bug in this plugin:

WordPress verze 5.8
Aktuální šablona: Twenty Twenty (verze 1.8)
Aktuální plugin: WP Cerber Security, Anti-spam & Malware Scan (verze 8.9.3)
Verze PHP 8.0.9

Podrobnosti chyby
=================
Na řádku č. 291 v souboru /www/doc/www.autodopravajarni.cz/www/wp-content/plugins/wp-cerber/admin/cerber-tools.php došlo k chybě typu E_ERROR. Chybová zpráva: Uncaught TypeError: strip_tags(): Argument #1 ($string) must be of type string, array given in /www/doc/www.autodopravajarni.cz/www/wp-content/plugins/wp-cerber/admin/cerber-tools.php:291

Anyway, the site works and you can log in via /wp-admin, so the error is obviously not serious.

Please help.

Thank you.
