Error in UI when searching in the Pages widget for?


(Jeff) #1

When searching in the pages widget in the UI, I entered ?, searched and got a bunch of errors back. (I was looking for pages with query strings.) A similar set of errors happens when searching for other characters like [ and *

One of the stack traces (they are all pretty much identical):


There is an error. Please report the message (Piwik 2.4.1) and full backtrace in the Piwik forums (please do a Search first as it might have been reported already!).

 Warning: preg_match(): Compilation failed: nothing to repeat at offset 0 in ......\piwik\core\DataTable\Filter\Pattern.php on line 72

Not a big deal, but I thought you’d want to see it. Hope this isn’t a duplicate. I searched and didn’t find anything that looked the same.

Thanks for the report. This is a known bug that we’ll fix in coming release: Searching in datatable for `?param` results in error message · Issue #5949 · matomo-org/matomo · GitHub
