 * Hi
 * I’ve updated wordpress from 3.9.3 to 4.1.1. I’ve also updated the download manager
   plug-in from 2.6.4 to 2.7.88.
 * I’m getting a 404 error when I try and access the content created under the download
   manger plug-in. My Permalinks is set to “Post Name”.
 * I’ve updated my .htaccess file to have the following:
    <IfModule mod_rewrite.
   c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ – [L] RewriteCond %{
   REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.
   php [L] </IfModule>
 * in the folders:
    wwwroot\wp-content\uploads\download-manager-files\.htaccess 
   wwwroot\wp-content\plugins\download-manager\files\.htaccess
 * If I switch the Permalinks to default, I can view the content. I need to keep
   Premalinks at Post Name.
 * Can anyone suggest any solution? I’ve also switched to default and purged the
   cache but that hasn’t worked.
 * Regards
 * Michael.

 * Try taking a backup of the `.htaccess` file in your root, deleting it and then
   using Settings –> Permalinks –> %postname% to regenerate the `.htaccess` file.

 * Hi Barnez
 * I didn’t have a .htaccess file in the root folder. I’m currently hosting in Azure.
   I have a wwwsite folder and inside this I have the 3 wordpress folders.
 * I have already dropped a .htaccess file into the wwwsite folder, with the following
   content:
    <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule
   ^index\.php$ – [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME}!-
   d RewriteRule . /index.php [L] </IfModule>
 * Still seeing the same issue. Changed the permalinks to default, purged the cache
   and changed permalinks back to normal. I’ve also added custom and tag into the
   Custom and Tag base optional fields.

 * I should also highlight that I’m hosting the wordpress site on Azure.

 * That would be the reason why then as Azure does not recognise an `.htaccess` 
   file. Have a look at this post:

 * Hi Barnez
 * I’ve gone through the link. I’ve already got the web.config file in place (and
   it matches for the rules section, but uses a different name for the rule).
 * Unfortunately, I’m after inheriting the site so don’t have the background information.
   I had gone with the automatic upgrade approach when I upgraded on Friday.
 * Regards
 * Michael.

 * I see. there is also [this walk through](http://www.iis.net/learn/extensions/url-rewrite-module/enabling-pretty-permalinks-in-wordpress)
   but it seems to contain pretty much the same information. Are there any Azure/
   Wordpress specific forums you could post to?

 * This is frustrating. I’m considering revert the upgrade as the site can’t be 
   showing 404 errors.

 * Hi Michael.
 * That could be a temporary solution, and I hear your frustrations. The problem
   with running older versions of WordPress is of course the security aspect. What
   is often suggested is to set up a test site which mirror’s the production site,
   but allows you to explore and resolve issues such as this without affecting your
   live site and its traffic/SEO.
 * Regards,
    Barnez
