Website is down

Maybe the website you are trying to visit is restricted to certain countries other than yours or maybe there is something wrong with your ISP. The first thing you should do is to check whether the website is really down for everybody. Go to Downforeveryoneorjustme and enter the website's URL in the field (e.g. google.com) and press Enter.

If the website is up, you will be able to access it through a proxy server. Search for most popular and most secure proxy websites and try one of them.

If you use a router and you cannot load any website, probably the router itself is the issue. Maybe the Internet connection crashed and the router failed to re-connect or maybe it was something else that caused the router to stop working properly.

Restart the router by unplugging it from the power outlet (the easiest way), or by pressing the Power ON/OFF button (if available). Wait for 30 seconds to ensure all the power is gone and then plug it back in (or turn the power button on) again. After that, wait until the router reconnects to the Internet again.

If others can access the desired website (or your website) but you, there is a possibility that the hosting server of the website is blocking your IP address, or there is something wrong with your ISP's (Internet Service Provider) settings.

Some website owners do this to prevent users from certain countries/location from accessing the website, or to restrict the number of visits (e.g. You get kicked out if you visit the website more than 10 times per day).

Try to access the website through a proxy website. Famous proxy websites include hide.me, hidemyass.com, proxysite.com. If you are not sure how to use the proxy website, they include video tutorial for that purpose. Please note that this is a short-term solution to your problem.

To fix it long-term, contact your ISP first and then the server admins / hosting provider of the page you're trying to access to check why they are blocking you.

If your website is slow or goes down frequently due to a large number of visitors (or something else), this might be a hosting-related issue, i.e the hosting plan doesn't meet your needs.

The best solutions include upgrading the already existing hosting plan (by selecting more expensive packagages than the already selected one) or changing the hosting provider.

Famous hosting providers include: Hostgator, Bluehost, Ideahost, iPage, Hostclear etc.

A faulty plugin might be the reason for the website being down.

To solve this problem, update all the plugins. If that doesn't work, deactivate the recently added ones to see if that helps.
Find the section labeled plugin(s) in the admin panel of your website and read the plugin's functions carefully before you decide to disable it.

Note: Usually you can reach the admin panel by entering your website's name followed by /admin.php or /wp-admin (Wordpress users) or another extension (e.g. www.xyz.com/admin.php)

If you have your own server and you host your website on it, and your website started misbehaving after the number of visitors on it increased, then it is probably a server-related issue.

The RAM memory is one of the most important components of a server (along with the CPU and the hard drives). If the website consumes more of the RAM memory (provided that you checked the available RAM in the server's control panel), consider:

• Locating the culprit (e.g. a faulty plug in, or a virus) that consumes more of the RAM memory
  
  
• Redesigning the website (by excluding unnecessary memory-consuming add-ons)
  
  
• Upgrading the RAM capacity (If you tried the previous solution and none of them worked)

Note: If you are not sure how to do this on your own, ask an experienced friend or an expert.

One of the most common causes of the 403 Forbidden error are incorrect file permissions settings. This error message is displayed to protect you against hackers, i.e. for security reasons.

To correct this error, check if any file's or folder's permission is set to 777 (which means that everybody can edit it). If you detect a file or a folder with those settings, change the value 777 to 750 or 755 (for folders) and to 644 (for files).

The error 406 Not Acceptable is usually caused by the mod_security settings of your website. Mod_security is a type of a firewall, which scans for violations of the already-set rules. If an action that violates one of these rules occurs, the server will throw a 406 error. By default mod_security is enabled on all accounts. However, some programs require mod_security to be disabled.

You can disable the mod_security via ModSec Manager , or if you don't have the Modsec manager at your disposal, read this article.

A corrupted .htaccess file is one of the factors responsible for the 500 Internal Server Error. It may have become corrupted after you have installed a plugin or made another change to your WordPress site.

To fix this error, you need to create a new .htaccess file. To create a new .htaccess file:

1.  Open the WordPress root directory in FileZilla (click here if you don't know how to install and configure it) or your preferred FTP client (a software which uses the FTP- File Transfer Protocol to transfer files to and from a remote computer)
   
   It is typically called public_html. If you see folders named wp-admin and wp-content, you’re in the right place. If you can’t find the .htaccess file, click Server  and select Force Showing Hidden Files.
   
   
2.  Once you find it, rename it into .htaccess.bak
   
   
3.  Log in and go into your website's admin area (e.g. in case it's a Wordpress site www.yoururl.com/wp-admin), and then go to Settings -> Permalink
   
   
4. Scroll down to the bottom of the page, and click Save Changes
   
   
5. Open your website, which should be working fine.

A low PHP Memory Limit is one of the factors responsible for the 500 Internal Server Error. To fix it:

1.  Open the WordPress root directory in FileZilla (click here if you don't know how to install and configure it) or your preferred FTP client (a software which uses the FTP- File Transfer Protocol to transfer files to and from a remote computer).
   
   
2. Locate the wp-config.php file, download it and open it in Notepad or other text editor (right-click on the file -> Open with -> Select a text editor)
   
   
3. Add the following code and save the file:

   define('WP_MEMORY_LIMIT', '64M');

4. Re-upload it to wordpress (by selecting the upload option) and overwrite the original file
   
   
5. Try opening your website in a web browser

Note: If this didn't fix the error, remove the above-mentioned code from the wp-config.php file, save it, and re-upload it to the root directory.
