$maxRecursionDepth is a configuration parameter that sets the recursion depth for a template output, e.g. result format "Template"Uses a specified template to format and display the results. The configuration parameter was introduced in Semantic MediaWiki 1.4.0Released on 21 November 2008 and compatible with MW 1.13.x - 1.16.x..
Some query printers may return wiki code that comes from other pages, e.g. from templates that are used in formatting or from embedded result pages. Both kinds of pages may contain inline queries that do again use new pages, so we must care about recursion. We do so by simply counting how often this method starts a subparse and stopping at depth "
There is one special case: if this method is called outside parsing, and the concrete printer returns wiki text, and wiki text is requested, then we may return wiki text with sub-queries to the caller. If the caller parses this (which is likely) then this will again call us in parse-context and all recursion checks catch. Only the first level of parsing is done outside and thus not counted. Thus you effectively can get down to level 3.
$maxRecursionDepth = 2;
This means that by default a recursion depth of two is permitted which effectively works until the third level of parsing.

Changing the default setting
To modify the setting to this configuration parameter, add the following to your "LocalSettings.php" file after the
- Allow a recursion depth of e.g. three
SMWResultPrinter::$maxRecursionDepth = 3;
- Information on the limitations to the template format
- Task T43268 - Discussion regarding this configuration parameter.
