I have recently purchased a Windows VPS with Plesk control panel and have uploaded website files. While visiting my website it is asking for username and password authentication. Now, I haven’t set any authentication on server for any website, what shall I need do?
This is quite common with the sites hosted on windows server with plesk as a control panel. You are not allowed to acces the site whtout authentication – entering username and password. This is not a bug or issue but is related to password synchronization with IIS server. To resolve this, you will need to synchronize the password.
Below given are some simple steps that you will need to follow:
The above command will synchronize the password and you will require no more password authentication to view the content.

You have the GD image library installed and otherwise working.
Still unable to get captcha with the captcha plugin.
You are not sure what’s the problem as it works on one of your other sites. When you try to include the captcha on your website or contact form it generates an error message like…
Call to undefined function imagettftext() OR
Fatal error: Call to undefined function imagettftext() in /home/user/public_html/appfolder/plugins/captcha/captcha.php on line 99 OR
Fatal error: Call to undefined function imagefttext() in /home/user/public_html/lib/captcha/captcha.php on line 329 OR
‘–enable-gd-native-ttf’
Problem could be, because the standard PHP “imagefttext()” function does not work on your server.
It can caused by the fact that there is no –enable-gd-native-ttf key installed on your server as the Cart uses GD Library for displaying the verification image.
Please note that PHP must be configured with the following keys:
–with-gd –enable-gd-native-ttf Contact your host to make the change!
Any idea why or how it can be fixed?
imagettftext() is part of the GD image functions library, which is not always part of PHP (the code CMS/Cart runs on).
You need to contact your host and ask them to install the PHP GD library. It’s really simple for them to do and is fairly common, so if they give you a hard time about it, I would seriously consider switching to better and friendly host – UnicHost :).

Clear the history for current login or current user.
#history -c
First find the history file for particular user.
Delete .bash_history file, will be recreated again next time.
#locate .bash_history
#rm .bash_history
It is not a best practice to totally disable the ssh command history on any dedicated server or vps server. It’s a quick reference to user’s past actions on server.
