    Internal server errors (error 500) are often caused by plugin or theme function conflicts, so if you have access to your admin panel, try deactivating all plugins. If you don’t have access to your admin panel, try manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.

    If that does not resolve the issue, try switching to the default theme for your version of WordPress to rule-out a theme-specific issue. If you don’t have access to your admin panel, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue.

    If that does not resolve the issue, it’s possible that a .htaccess rule could be the source of the problem. To check for this, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, and rename the .htaccess file. If you can’t find a .htaccess file, make sure that you have set your SFTP or FTP client to view invisible files.

    Hi,

    Thank you for your help.

    I have in detail .htaccess please check below :

    # BEGIN WordPress
    <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.php$ – [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]
    </IfModule>

    # END WordPress

    There is nothing else. We have used very less plugins
    1) windows-azure-storage 2) wp-super-cache

    We are using Paid Redux Framework in wordpress.

    We have some one main domain right now and we have redirected other sub domain to this main domain. through web.config file.

    How can I check confliction of function.php ?

    Can you please help me, I have added more in detail.

    Thanks.

    Hi,

    I have updated my wordpress version to 4.6.1. Now I have checked log files where i got more errors.
    please check some of them in details :

    mysqli_real_connect(): (HY000/2002): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

    Cannot redeclare register_rest_route() (previously declared in D:\home\site\wwwroot\wp-includes\rest-api.php

    Can you please help me why these is occurred and is this pointing to my first concern ‘internal server 500’

    Thanks,
    Swapnil
