It was hosing the page. I had to rename ditto 1.0.2 to something else and let ditto 2.0.3 be [[Ditto]] and the call worked and the template shows correctly.
However, I have many ditto calls still using the 1.0.2 parameters. However, MaxiGallery, RandomQuote and GetField snippets are showing instead of being processed. In the case of the MaxiGallery calls, the call is within a Ditto template. So is the GetField call. Is there a problem with snippet calls nested in a ditto tpl? Or is there something in general that would be causing the other snippet calls not to be processed?
Thanks.
To add support for Ditto 1.x parameters just add &config=`compatibility` to the Ditto 2 call or to enable it across all Ditto 2 calls rename the compatibility.config.php to default.config.php (replacing it).
