Resolution

You may configure site's publishing settings through Parallels Plesk Sitebuilder control panel at Sites -> <site name> -> Publish Settings.

"Publishing mode" is method how files are uploaded to publish host. It can be FTP, VPS, or XCOPY. For details please see article specifying hosts used for publishing sites in Parallels Plesk Sitebuilder Administrator’s Guide.

Here is example for configuration of FTP publishing:

"Host" is IP address or hostname where files are uploaded via FTP
"Port" is post for FTP connection
"Login" is FTP login for files uploading
"Password" is password for FTP login
"Working directory" is location under FTP user's root directory where files are uploaded
"Web site URL" is URL to access the site

For example:

"Publishing mode" FTP
"Host" xxx.xxx.xxx.xxx
"Port" 21
"Login" ftp_login
"Password" ftp_password
"Working directory" /httpdocs
"Web site URL" http://domain.tld

To test FTP location is set correctly login to the FTP location upload a test file to the location via FTP using login credentials specified. Check that the file is available via  http://domain.tld/test.file.

Also check that domain.tld is resolved to single IP address xxx.xxx.xxx.xxx:

~$ host domain.tld
domain.tld has address xxx.xxx.xxx.xxx
~$

 If the domain name is resolved to several IP addresses this may cause non-permanent problems in verification of publishing location. Publishing may fail from time to time.

Also it is recommended to verify that publishing server is configured correctly. List of requirements to publishing host you can find on our website here: http://www.parallels.com/products/plesk/sitebuilder/reqs/

There is a special script which can help you to check if everything is fine with requirements: SITEBUILDER_ROOT/resources/publish/check.php. It should be run from publishing site's directory.
SITEBUILDER_ROOT - Sitebuilder installation directory /usr/local/sitebuilder/ or /opt/sitebuilder/ on Debian/Ubuntu servers.

For example, if you are trying to publish to domain domain.tld you need upload this script into site's directory and run it in browser as http://domain.tld/check.php.

As an example, you can find correct output below:

ioncube=ok phpVersion=4.4.3 mbstring=ok zlib=ok session=ok dom=ok domxml_xslt=ok sqlite=2.8.17 sqliteEncoding=UTF-8 gd_png=ok gd_gif=ok gd_jpg=ok gd_wbmp=ok gd=2.0.28 safe_mode=ok mail=ok serverApi=Apache  Handlerfolder_permissions_data=ok
 
NOTE:
 1. Publication works with safe_mode 'on' since Parallels Plesk Sitebuilder version 4.0. So if you have version 4.0 or newer you do not need to worry about safe_mode=failed output.
 2. Parameter folder_permissions_data is actual for publishing to Windows servers, so if you see that folder_permissions_data=fail, you can ignore this output.
