Step 2: Click the menu icon in the upper right corner of chrome. Then select settings, then select Show advanced settings. On this window, uncheck the box Offer to translate pages that aren’t in a language you read.

Step 3: Perform login again.

2. Lỗi “This is a placeholder for the subdomain…”

You take the following steps to fix the error:

Step 1: In, go to public_html.

Step 2: The demo folder appears on the screen. Including the file index.html

Step 3: You can delete the index.html file

3. Lỗi “mod_fcgid: can’t apply process slot for”

When you use directadmin that sees the message mod_fcgid: can’t apply process slot for, you need to do the following steps to fix it.

In case you use Hosting, you need to check if you have configured correctly. If you still see an error, you need to contact your hosting provider to ask if CGI Access is enabled on the host. If you use VPS, you need to adjust the MaxProcessCount parameter located in /usr/local/apache/conf/php.conf.


# Fastcgi configuration for PHP5

LoadModule fcgid_module modules/

MaxRequestsPerProcess 500

MaxProcessCount 3

MaxRequestLen 33554432

IPCCommTimeout 60

IdleTimeout 120

IdleScanInterval 30

BusyTimeout 120

BusyScanInterval 90

ErrorScanInterval 3

ZombieScanInterval 3

ProcessLifeTime 3600

If it still doesn’t work, try delegating 775 for FastCGI login

4. Lỗi No input file specified

Lỗi No input file specified

Lỗi No input file specified

This is the error caused by apache. To fix the error, refer to the following 3 ways:

Way 1: Go to file .htaccess add ? after index.php before “/”

for example the following code:


RewriteEngine On

RewriteCond %{REQUEST_URI} ^/system.*

RewriteRule ^(.*)$ index.php?/$1 [L]

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^(.+)$ index.php?/$1 [L] 

Method 2: Maybe in the process of adding the domain there is an error. So try deleting the domain and adding it again.

Method 3: In case you cannot edit the .htaccess file, you can follow these 2 steps:

Step 1:

PHP runs in CGI mode when cgi.fix_pathinfo is set to 1. Open /system/application/config/config.php or where the config file is located and make sure these two options are set.


$config['index_page'] = “”;

$config[‘uri_protocol’] = “AUTO“; 

Step 2:

Create a PHP.INI file under your website root directory with the content


cgi.fix_pathinfo = 0;

5. Lỗi Nginx is functioning normally

Lỗi Nginx is functioning normally

Lỗi Nginx is functioning normally

During use, you will occasionally encounter Nginx is functioning normally. Fix it in the following ways:

  • If this error appears due to not assigning IP to the correct domain, you need to reassign the IP to the correct domain to fix the error.
  • When you just point the domain name to the hosting without adding the domain on the hosting or creating a domain on the VPS/Server is also a cause of the error. Nginx is functioning normally. So you need to add hosting to solve the error.
  • If the above 2 methods still do not make the error disappear, you need to contact your hosting provider for support.

6. Lỗi An error occurred while creating the compressed file

The cause of this error is that you try to compress the file above DirectAdmin but using too much storage space. To handle this error, you need to delete unnecessary files to free up space on your hosting or increase your hosting capacity by contacting your hosting provider to buy more space. You can use one of these two ways, but make sure the free space is larger than the size of the file you compress.
