Since adding charts to the stock ticker in version 2.5 we have some reports of users not being able to get all the charts that they need. Yahoo! has at least two interfaces for their charting and it appears that not all stocks world wide work depending on the interface that you use.
So in this update we’ve given you the ability to select between the two Yahoo! interfaces. If the stocks you would like to display don’t work on the first one then try the alternative interface.
The selection of Yahoo! interface is made on the WP Stock Ticker options page, see below for a screen shot.
How to update
Users of version 2.5 will be able to download the update simply by visiting the Plugin screen in your WordPress Dashboard, 2.6 will be listed as an update.
Users of older version need to download the plugin by logging into your account here on HelpForWP.com and then visiting the Purchase History section.
