Error occurred while validating HTTP header: cookie. HTTP header value: cookie [............]
Hi,
on TW Foundation 8.4.3 i found this error, logged in "Application logs" several time per minute.
Error occurred while validating HTTP header: cookie. HTTP header value: cookie: Invalid input. Please conform to regex ^[a-zA-Z0-9()\-=\*\.\?;,+\/:&_|% ]*$ with a maximum length of 1000.
i found also a possible answer here, but it doesn't help, since the error persists.
Thanks in advance.
