This is usually seen when some memory issue occurs, e.g. due to more source code being loaded now. You can try to increase the PHP memory limit in LocalSettings.php (where requirements above 50M are unusual even if you use normal-sized queries; I found it needed on some wikis that create very long/broad result tables but basic operation should usually work with 20M). > > With the debug output format I don't get any errors and I can also past the > SQL query into MySQL and get the desired rows, so up to the database query > it runs fine.

This is strange and could hint at a URL encoding problem. Can you reproduce the problem on sandbox.semantic-mediawiki.org? The code for Special_Ask was recently extended by Yaron, so maybe he has an idea if this could be related. > > @Markus: > On Bugzilla Philipp filed the bug 21232 in October, asking for chained > property value printing which is a pretty important feature for my use > case.

But implementing it will be some work as it requires an extension not only in the result retrieval, but also in the parsing of query parameters and in the data structures that represent print requests for queries.
