• Hi, Pleskians! We are running a UX testing of our upcoming product intended for server management and monitoring.
    We would like to invite you to have a call with us and have some fun checking our prototype. The agenda is pretty simple - we bring new design and some scenarios that you need to walk through and succeed. We will be watching and taking insights for further development of the design.
    If you would like to participate, please use this link to book a meeting. We will sent the link to the clickable prototype at the meeting.
  • (Plesk for Windows):
    MySQL Connector/ODBC 3.51, 5.1, and 5.3 are no longer shipped with Plesk because they have reached end of life. MariaDB Connector/ODBC 64-bit 3.2.4 is now used instead.
  • The Horde webmail has been deprecated. Its complete removal is scheduled for April 2025. For details and recommended actions, see the Feature and Deprecation Plan.

Please I need help in resolving this issue.
Did I need to add this rule to exempt it or this is a malecious activity.
I found out that all visitors having this issue has this cookies "twk_uuid_5ba4c8f8c9abba579677c378" in there browser.
When I manually delete the cookies, the website will open.
I don't know how this cookies is getting into the browser
 
Thanks very much. What I did was to except OWASP_CRS rule. So everything works after that.
Though am still studying the implications
