hi there.
after i install views_mode and the required module is purl. somehow my Views is not right.

when i wanted to add filter criteria and choose the field, and after i click Add and configure filter criteria, there is a white screen and a long text in one row at above of the screen written this

[ {"command":"settings", "settings":{"basePath":"\u002F", "pathPrefix":"", "ajaxPageState":{"theme":"seven", "theme_token":"7USPHajocQCz31Egs836_mC0SxNCcZHlVHvjGR9Ax74"}, "CTools":{"dependent":{"edit-options-value-value":{"values":{"edit-options-operator":[ "\u003C", "\u003C=", "=", "!=", "\u003E=", "\u003E", "regular_expression" ]}, ......... and summore text its very long to paste here.

im using:
drupal 7.15
views 7.x-3.5
Persistent URL tests 7.x-1.0-beta1

this is fresh install, and only one content type created, and im using sub-theme of adaptive theme.
