Last night everything worked fine, this morning I tried logging in to my email/horde and I got a fatal error message. I checked my server-manager for updates and completed shown updates. After updates/reconfigure, I attempted to log in again to email, and I still get the same massage:
A fatal error has occurred
"dynamic/sidebar.html.php" not found in template path ("/home/httpd/html/horde/templates/:./")
Details have been logged for the administrator.
