Support: PowerStore 4

Yes, you can upgrade your PowerStore 2 or PowerStore 3 site to use PowerStore 4. PowerStore 4's Installation Wizard will automatically upgrade a PowerStore 3 site to PowerStore 4 if you enter the PowerStore 3 database credentials on the database step. For PowerStore 2 users, you will first need to follow the tutorial for upgrading to a PowerStore 3 database, prior to running the PowerStore 4 Installation Wizard (see 'Archived Documentation'). After running the script and updating your database, you will be able to run the Installation Wizard and enter your PowerStore database credentials on the database step to have your database automatically updated.

The WebAssist Extensions have been used to apply functionality throughout the WebAssist Solutions. In many cases, you can use your extensions to modify the functionality of the Solution Pack to suit your needs. These customizations are not supported by WebAssist staff and require you to have a solid understanding of how the changes you make will affect the Solution you are modifying.

There are an endless number of modifications that can be made to a Solution using a WebAssist Extension. However, in order for someone to succeed with modifying a Solution with a WebAssist Extension, make sure to complete these steps:

1. Become familiar with the extension you are going to use before attempting to make changes.
   
   Refer to each product's Getting Started Guide for information. In particular, note how to reenter the product's interface to make changes. If you have never used the particular extension before, you should probably learn by applying the product to a separate site before changing the Solution Pack functionality.
   
   
2. Define a Dreamweaver site where the solution pack files are at the root of the site.
   
   This is necessary for WebAssist extensions to find the appropriate files for making any modifications.
   
   
3. Set up a local testing server for running PHP and MySQL if necessary.
   If you intend to make dynamic changes that will need to reference your database, you will likely need to have defined a testing server.

   See Setting up a Testing Server for Windows or Setting up a Testing Server for Mac OS X for more information.

Note: To avoid breaking functionality in the Solution, it is important that you become familiar with the Extension first.  You should also confirm that the particular extension was used when creating the solution before trying to use it for making changes.

If, when previewing your contact form on your local testing server, you find the Captcha graphic is not displaying, you may need to enable the GD library on your local web server.

If the rate that is being returned differs from what you are receiving from UPS, it is likely due to the type of service you are receiving from UPS. The rate that is retrieved through the UPS API assumes that you have a UPS Account where your packages are picked up for delivery on a regular basis.

You may want to review some settings on the UPS calculator to obtain matching rates.

Make sure that you have read/write permissions to the Images/Upload directory. Otherwise, you will encounter this error when trying to upload an image for a product. For information on configuring File Permissions on your live server see the video on the PowerStore video tab.
