• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Horde in 11.5 prevents some attachment viewing

HostaHost

Silver Pleskian
Version: 11.5.30 CentOS 6 115140407.17 x86_64

Description: On prior versions of Plesk, users could attach Microsoft Office (word, excel, etc) files to messages they are composing in Horde, and then, before sending, click on those attachments to view them to make sure they are correct. After upgrading to 11.5, the following error is shown in Horde instead:

"Fatal error has occured could not display attachment. Details had been logged for the administrator."

This issue does not occur with other file types, such as a PDF or text file.

Steps to reproduce: Install Plesk 11.5 on Centos 6 x64, create an email in Horde, attach a Word document, before sending, try to view the document.

ACTUAL RESULT: Fatal error has occured could not display attachment. Details had been logged for the administrator.

EXPECTED RESULT: View the document.
