You can redirect all of the requests for www.yourdomain.com domain to yourdomain.com by modifying your website's .htaccess file. You need to add the following lines at the beginning of the file in order to setup that redirection:


RewriteEngine on
RewriteCond %{HTTP_HOST} ^www.yourdomain.com [NC]
RewriteRule ^(.*)$ http://yourdomain.com/$1 [L,R=301]

Avoiding the Not Secure Warning in Chrome

Chrome will have following impact after the version 65:

1. The websites that having Symantec-issued TLS certificates older than June 1, 2016 and that must be replaced
2. Chrome will mark non-secure pages containing password and credit card input fields as Not Secure in the URL bar.

To avoid this you need to install the SSL on the website that contains containing password and credit card input fields. 

For testing:

1. Please install the updated version of chrome - https://www.google.com/chrome/browser/canary.html
2. Configure Chrome to show the warning as it will appear in January 2017, open chrome://flags/#mark-non-secure-as and set the Mark non-secure origins as non-secure option to Display a verbose state when password or credit card fields are detected on an HTTP page. Then relaunch your browser.

WordPress - Briefly unavailable for scheduled maintenance. Check back in a minute.

Briefly unavailable for scheduled maintenance. Check back in a minute.

How to fix it.

When this happens, WordPress generates a .maintenance file in the root directory of the installation. With normal behavior, the update script completes and WordPress auto-removes the .maintenance file. In the case of an interruption of some sort, this file doesn’t get deleted and the message won’t go away.

The answer? Delete it manually.

Here are the steps:

• Log into your web server via FTP or your web host’s control panel.*
• Locate the root of your WordPress install (this is where you’ll find folders for wp-content, wp-admin, and wp-includes)
• Look for a file called .maintenance
• Delete it

Upload Multiple Files Using FileUpload Control In ASP.NET 4.5 +

ASP.NET 4.5 and upper versions support this feature.

Now, FileUpload  control is built to support HTML 5, therefore it is only supported in browsers supporting HTML5. For other browsers it will work like a normal file upload control in ASP.NET.

A new Attribute introduces with the ASP.NET 4.5 FileUplaod control i.e. AllowMultiple, It takes either true or false.

In order to support multiple file uploads, set AllowMulitple="true" other than false.

<asp:FileUpload runat="server" ID="UploadImages" AllowMultiple="true" />

In addition to this control, some new properties have been included to support code-behind coding.


HasFilesCheck whether FileUpload control has multiple files or not.

PostedFilesBasically used to get all the files from the FileUpload control in the iteration.

Example code to upload files:

   <asp:FileUpload runat="server" ID="UploadImages" AllowMultiple="true" />  
   <asp:Button runat="server" ID="uploadedFile" Text="Upload" OnClick="uploadFile_Click" />  

protected void uploadFile_Click(object sender, EventArgs e) {  
    if (UploadImages.HasFiles) {  
        foreach(HttpPostedFile uploadedFile in UploadImages.PostedFiles) {  
            //code to save files  
        }  
    }  
}
