Updating the Slider PRO plugin

1. Updating to version 4.0

Version 4.0 is dramatically different from the versions 3.9 and older, so an automatic transfer (like in previous updates) is not possible, BUT they can run in parallel. My advice is to continue using the old version for your current sliders and use the new version for your future sliders.

The old Slider Pro will continue to be maintained, which means that there will be future updates for it, to ensure compatibility with future WordPress versions. In version 3.9 (released on April 15th, 2014) automatic updates were introduced, so future updates for the old Slider Pro will be available directly from the WordPress Dashboard. If you’re currently using a version older than 3.9 you will first need to update to 3.9 and then you can activate automatic updates. I’ve set up a webpage where you can download the old version, since on CodeCanyon you can only download the new version. You will need to provide your username and purchase code: http://bqworks.com/slider-pro/legacy/


2. Updating from version 2.x.x or 3.x.x to version 3.9

Before updating, don't forget to create backups of your custom CSS or JavaScript code, custom skins, and modified skin files.

For updating the plugin, it's recommended to follow these steps:

  1. Deactivate the plugin.
  2. Use FTP to connect to your server and navigate to /wp-content/plugins/.
  3. Unzip slider-pro.zip and copy the new slider-pro folder in /wp-content/plugins/, overwriting the existing slider files.
  4. After all files have been copied, activate the plugin again.

As an alternative to uploading all the files, you can upload only those that were modified or added. However, if you want to use this method, please make sure you updated all the mentioned files.


3. Updating from version 1.x.x to version 3.9

Before updating, I recommend creating a backup of the current sliders by saving the sliders' XML files (slider-pro/xml) in a safe folder. In case something goes wrong during the update, you can recreate all your sliders using those XML files. You may also want to backup your skin files if you made any custom edits to them.

The following steps are required when you update:

  1. Deactivate the plugin.
  2. Use FTP to connect to your server, go to /wp-content/plugins/.
  3. Unzip slider-pro.zip and copy the new slider-pro folder in /wp-content/plugins/, overwriting the existing slider files.
  4. After all files have been copied, activate the plugin again.

Please note that, in newer versions, modifications were introduced to the names of some slider options and CSS selectors, which were meant to make the slider more intuitive to work with.

One of the most important changes is the role of the 'Width' and 'Height' options. These options no longer refer to the width and height of the slide image, but rather to the width and height of the whole slider, which includes controls, shadow, thumbnail scroller, etc. This modification was introduced in order to allow the slider to be responsive. When you want to determine the required width and height that you need to set the slider to in order to have a certain width and height for the slides, you can use the Preview window. In a later chapter, I will show you how to use this window in order to have the slider sized exactly as you want.

1. Options Modifications

While there are a few options which had their name slightly changed, it's not important to enumerate them, because the slider will automatically handle this modification.


2. CSS Modifications

The CSS updates will need to be done manually if it's the case. The following CSS selectors were changed:

  • .skin-name .navigation-arrows -> .skin-name .slide-arrows
  • .skin-name .caption .background -> .skin-name .caption-container .background
  • .skin-name .caption .content -> .skin-name .caption-container .caption
  • .skin-name .navigation-buttons -> .skin-name .slide-buttons
  • .skin-name .navigation-buttons .buttons -> .skin-name .slide-buttons .buttons-inner
  • .skin-name .navigation-buttons .buttons .thumbnail -> .skin-name .slide-buttons .buttons-inner .thumbnail-wrapper
  • .skin-name .navigation-thumbnails -> .skin-name .thumbnail-scroller
  • .skin-name .navigation-thumbnails .thumbnail -> .skin-name .thumbnail-scroller .thumbnail-wrapper

4. Activate automatic updates

After you update to version 3.9, you can activate automatic updates. First, you need to add your purchasing code in the Slider PRO -> Plugin Options page. The purchase code can be found on CodeCanyon.net

Then, you need to move some folders that contain custom assets in a separate folder, outside the main plugin folder, in order to avoid having these custom files removed. This can be done automatically, by the plugin, or, if the folder permissions on your server don't allow the plugin to create the folder automatically, you will need to create them manually.

The folders that need to be moved are 'custom', 'skins' and 'xml' from 'wp-content/plugins/slider-pro' and then need to be moved to 'wp-content/slider-pro-assets'.

NOTE: If the slider seems broken after an update or you don't see the new changes, please try clearing the browser's cache.
