Just a CS3 update.
1. Cleared WinCache.
2. Started with a blank PHP file.
3. Created and Applied new API to Create A Bing Search Page tool
4. Completed the form entries and clicked OK.
( Search Page and Results Page = bing_search.php )
I got the following error...
I realize I have limited to no support as CS3 is not supported. I just wanted to provide this update.
