====== SSL certificate exceptions in Zotero Standalone ====== 

**Note:** These instructions are generally for WebDAV servers only. You should never whitelist the Zotero sync server certificates unless you [[kb:ssl_certificate_error|understand the consequences]].

Zotero Standalone does not currently provide a graphical way to whitelist self-signed certificates of WebDAV servers, as is possible in Firefox.

If you use a WebDAV server with a self-signed certificate, you can open the WebDAV URL in Firefox, accept the certificate, and then copy the cert_override.txt file from the [[http://support.mozilla.com/kb/Profiles|Firefox profile directory]] to the Zotero Standalone profile directory, located at one of the following paths:

Mac OS X:\\
  /Users/<username>/Library/Application Support/Zotero/Profiles/<randomstring>

Windows Vista and 7:\\
  C:\Users\<User Name>\AppData\Roaming\Zotero\Profiles\<randomstring>

Windows 2000 and XP:\\
  C:\Documents and Settings\<username>\Application Data\Zotero\Profiles\<randomstring>

Most Linux distributions:\\ 
  ~/.zotero/Profiles/<randomstring>
