500 Internal Server Error - GoDaddy flesk server

Question

I have developed WordPress site which is working fine. When I moved it to GoDaddy flesk server and try to create/edit WordPress post or page - It gives following error:

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator to inform of the time the error occurred and of anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

My .htaccess file is:

# 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

and web.config file is:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>  
<rewrite>
<rules>
<rule name="WordPress Rule" stopProcessing="true">
<match url=".*" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="index.php" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>

Any help will be appreciated. Thanks

Answer 1

Finally, I have found the solution of it. Just I have added <httpErrors errorMode="Detailed" existingResponse="PassThrough"/> in web.config file as: Get detailed errors

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
    <httpErrors errorMode="Detailed" existingResponse="PassThrough"/>
<rewrite>
<rules>
<rule name="WordPress Rule" stopProcessing="true">
<match url=".*" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="index.php" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <httpErrors errorMode="Detailed" existingResponse="PassThrough"/>
    </system.webServer>
</configuration>

It gives following fatal error;

Fatal error: Class ‘MPCETemplate’ not found in C:\XXX\XXX\XXX\XXX\wp-content\plugins\motopress-content-editor\includes\ce\Library.php on line 1989

Solution: Actually, the issue was in PHP code. Library.php was missing in motopress-content-editor plugin.

Just I logged in WordPress admin panel and deactivate this motopress-content-editor plugin. It's started working.

Remove the extra/empty newline before and after "# END WordPress". It should resolve the issue.

# 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
