Apologies to everyone who installed yesterday’s release (0.3.14), this mornings release (0.3.15) should bring back the custom fields functionality. I was obviously a little premature in marking that one stable. Thanks to Vytautas for pointing out the issue.
Also, the previous release fixed some problems with the method of including search forms in posts and pages. To fix this bug though I have had to change the syntax for including presets in posts, please check the “settings/wp custom fields search” section of the site to see the new syntax. The old method is now deprecated (meaning it works for now so that everyone has a chance to update, but I will remove it soon.)
Basically what was:
[ wp-custom-fields-search preset="1"]
