I am getting this error a number of times a day.

[22-Jan-2026 22:33:29 UTC] PHP Warning: unserialize(): Error at offset 0 of 15 bytes in /home/panhandletractor/public_html/wp-content/plugins/bulletproof-security/bulletproof-security.php on line 237

Any thoughts what is causing it. I know it’s only a warning but slowly fills error log.

Do you have the LiteSpeed Cache plugin installed? If so, see this forum topic > https://forum.ait-pro.com/forums/topic/unserialize-error-at-offset-0-of-15-bytes-in-bulletproof-security-php-on-line-237/
