However, it’s important to note that Zen Cart’s Missing Page Check can only check for missing pages that are within the Zen Cart structure.  In other words, the check is carried out on the part of the URL that is after index.php?main_page=.  Such as http://www.zen-cart.net/demo/index.php?main_page=page8 or http://www.zen-cart.net/demo/index.php?main_page=jdfjkdklf.

In this case, you will be redirected to either a Page Not Found page or the Home Page according to your setting in Zen Cart Admin.  An example of the Page Not Found page is shown here:

Zen Cart cannot prevent a call to a html page or image file, for example, that are outside of the Zen Cart code.  This means that trying to access an invalid URL such as http://www.zen-cart.net/demo/frogs.htm or http://www.zen-cart.net/demo/frogs.jpg would result in a standard 404 Page Not found error, as shown in the example below:

Due to the nature of an ever-changing online store, it is important that we do not leave our visitors at the dead-end of a 404 Page Not Found error.  Next up, we will look at a couple of different options to avoid displaying these errors to our visitors.

The Page Parse Time information consists of three page statistics:

1. The page Parse Time is the time it took from when the first line of code in index.php started processing until the footer of your page was drawn. This includes the delays introduced by any SQL queries waiting on the database.

   The parse time is shown in seconds.

2. The SQL queries counter or Number of Queries is the number of hits on the database in order to retrieve the required data to build and display the page.
3. The SQL Query Time is sum total of the time taken for each of the SQL queries to run – from the time of sending a query until the results are returned – that are required to build and display the page.

See Turn on or off the display of the page parse time if you wish to enable or disable the display of this information.

Your Zen Cart store consists of PHP and other files that makes your store work together with the template files and these are all hosted on your web server.  There is also the MySQL database that contains all your products, orders, customers, and settings information.  As you customise your store you may end up changing a number of PHP and CSS files.  And as you configure your store, add products and make sales there are certainly many updates made in the database.  So you can see that it is important to take a backup when a change is made, such as the installation of a new add-on (module) or template, and also to continue to backup your store on a regular basis so that current customer and order information is included.

To do a complete back up of your Zen Cart store:

1. Back up the Zen Cart Database
   See Back up the Zen Cart Database with phpMyAdmin for step-by-step instructions if your host provides cPanel and phpMyAdmin access.

   Or, you may wish to look at the Zen Cart Add On available – Backup MYSQL Plugin.

2. Back up the Zen Cart Files
   To take a backup of the Zen cart files you are, in effect, just copying the files to an alternative location for safekeeping.For step-by-step instructions, look at:
   • How to backup your Zen Cart Store Files & Templates using FileZilla
   • How to backup your Zen Cart Store Files & Templates using cPanel

You may wish to also regularly burn a complete backup of your Zen Cart store to CD or DVD to ensure that you always have a safe copy regardless of hosting problems or local computer problems.

4. Customising Zen Cart?
5. Installing & Configuring Zen Cart – Full Step-by-Step Guide

1. Log in to cPanel.
2. Click on File Manager.
   
3. Select the correct location of your Zen Cart install and click the Go button.
   
   Note:  Web hosts have their preferences in naming the folders that are your Internet folders. Look for a “www” or “public_html” or “htdocs” or “httpdocs” or “wwwroot” folder. These are some of the common folder names for what is referred to as the “Web Root”, which is where all your website content is served from. Your Zen Cart files will be in one of these folders.
4. If your Zen Cart files are in the web root, select all the files and folders by ticking the corresponding checkboxes.
   If your Zen Cart files are in a subfolder, you can select just that folder by ticking the corresponding checkbox.

   Then, click on the Compress icon in the top menu toolbar.
   

5. Select the preferred Compression Type and also change the name to something more meaningful for you.  Then click on the Compress File(s) button.
   
6. The compressed file is created:
   
   and when completed the Compression Results window will be displayed:
   
7. The compressed backup file is now available for you to download and store offline.  You will now either save the backup file to a folder on your local computer or burn a copy to CD or DVD.  The backup file can the be removed from your web host then in order to conserve space.

3. Uploading the Zen Cart files to your web server
4. Create the configure.php files
5. Download Zen Cart Installation Files

1. Open FileZilla.
2. In the Quickconnect section at the top of the screen, enter your Host, Username, Password and Port information and click on the Quickconnect button.  This information would have been sent to you when you first signed up for your web hosting agreement.  If you do not have this to hand, contact your web host.
   
3. Once connected, you will notice that the section on the left hand side of the screen is your local files (ie the files on your computer) and the section on the right hand side is your web host files (ie the files that make up your website).
   
4. Under the section Local Site, navigate to the location where you wish to save your Zen Cart backup files.  Create a new folder/directory.  It’s a good idea to include the date in the folder name to help you organise your backups as you go on.  Double-click on this new folder.
5. Under the section Remote Site, navigate to the location of your Zen Cart store.  Select the admin folder by clicking on it once.  Then select all files and folders by holding the Control (Ctrl) key on the keyboard while you press the A key on the keyboard (Ctrl-A).
   
6. Right click on the selected files and choose Download from the drop-down menu.
   
7. And that’s it.  All the Zen Cart store files and folders will download to the local folder specified.

You can now either zip up the backup files or burn a copy to CD or DVD.

Even if you are not making changes to your store, a backup should continue to be taken on a regular basis to ensure your backup includes up-to-date customer and order information in the event you do need to restore from the back up at any stage.

How often you backup your database depends on how active your store is.  It could range from monthly, weekly, daily to even hourly if you are processing thousands of orders every day.  If you are unsure, I would recommend you start with weekly database backups.

1. Log in to your cPanel Control Panel
   

   Your cPanel is located at either http://YourSitesIPAddress/cpanel (for example, http://1.2.3.4/cpanel), or http://www.yourdomainname.com/cpanel or http://cpanel.yourdomainname.com/.

   Your cPanel username and password will generally be found in a welcome email from your webhost.

   Scroll down to the section Databases and click on phpMyAdmin.
   

2. Select the Zen Cart database from the menu on the left hand side of phpMyAdmin.
   

3. The Zen Cart database tables will now be displayed. Click on the Export tab.
   

4. The recommended settings for your Zen Cart backup via phpMyAdmin are as follows:

   Structure
   Make sure the following have a tick in the checkbox:
   - Structure
   - Add DROP TABLE / VIEW / PROCEDURE / FUNCTION
   - Add AUTO_INCREMENT value
   - Enclose table and fieldnames with backquotes

    

   Data
   Make sure the following have a tick in the checkbox:
   - Data
   - Complete Inserts
   - Extended Inserts
   - Use hexadecimal for binary fields (or BLOB)

   Make sure the Export type is set to Insert.

   

5. Make sure Save as file has a tick in the checkbox and the File Name template is set to __DB__.
   Set the Compression to your preferred – “zipped” files are easier to read with Windows, “gzipped” will result in a smaller file.
    

   Settings not mentioned can be left at the default settings.

6. Click the Go button to back up your Zen Cart database.

7. If prompted, click OK to save the backup file.
   

8. Select an appropriate location to store your Zen Cart backup files.  You may also wish to burn a copy of the backup file to CD or DVD for safekeeping.
