Select XSLT File dialogue box does not allow selection of data source?

[gordon]

I have been building dynamic content in PHP pages using xsl fragments and this has been working fine. However, this is not working now. When I use the "XSL Transformation" dialogue and browse to select a created xsl file, the "Select XSLT File" dialogue gives this error.

 

To put dynamic data onto your page:

 

1. Define a database query by choosing Recordset from the plus(+) button in the binding panel, or by pasting a query from another page.

 

It does not allow me to select any data source

 

I suppose I accidently changed something to cause this to stop workign correctly. Any ideas?
