Recently we have found that many of Plesk users are complaining about receiving Blank Email to the Plesk Admin address like below
Unable to Access Plesk – PSA dead but subsys locked
Recently we faced a problem where Plesk was not accessible over Internet i.e. using port 8443 (https) and 8880 (normal). The first thing we checked was the Firewall; it happens sometime that the problem might be with firewall which was blocking port 8443 and 8880 but there was no problem with Firewall. Then we tried to check the status of Plesk (PSA) Service and got following response
Error: Unable to update FTP account: ftpmng –add-user failed
Sometime while creating Additional FTP account or Updating Domain user it shows following Error
HTTPD doesn’t start After Atmail Installation in Plesk
After installation of Atmail Webmail Client, while restarting Apache it throws following Syntax Error:
Cannot Connect to WMI Provider. You do not have permissions of the server is unreachable
Sometime while connecting to MSSQL Server Configuration Manager it throws following Error
Installation And Configuration of Mod_suPHP on Plesk (CentOS)
Introduction:
Whenever PHP runs as an Apache Module it get executes as “user/group” of the web server which is usually “nobody” or “apache”. SuExec is a mechanism supplied with Apache which allows executing CGI scripts as the user to which they belongs to, rather than Apache’s user. This improves security in possibilities where multiple mutually distrusting users can put CGI content on the server and these scripts are executed as the user that created them. If user “admin” uploaded a PHP OR CGI script, you would see it was “admin” running the script when looking at the running processes on your server? This also provides an additional layer of security where script permissions can’t be set to 777 (read/write/execute at user/group/world level).
