"No class specified for loadClass" - hosting environment issue?

[PuddingtonBeer]

A problem I'm sure several people have had, and discussed briefly on the modx forum. I imagine it prevents many people using this otherwise ideal extra, as I would, but for some reason nobody has reported it here.

I've installed this extra on two different sites, one hosted on shared hosting from one provider and the other on a custom virtual server of my own configuration (not far from default, but upgraded to PHP 5.4), from a different ISP, and both systems produce the same result. I'm not sure what's common to both configs.

Results from tests on PHP 5.3 from the first provider, shared hosting:

In the manager all is well, editing a term resource shows the resources allocated to the term on the 'Pages' tab, etc., but on term pages using the snippet [[!getPagesByTerm]] produces no content and the following stuff appears in the modx error log each time the page is refreshed on the frontend:

I used [[!getTaxonomies]] in the content of the parent categories resource which also produced no content, and the following in the modx error log:

Can confirm. I've got exactly the same problem. PHP 5.4.45
MODX 2.4.3

It would appear the default properties aren't set in the snippet.

Same issue here, and the options are being set... Any further details/input on this issue?

Same issue here. Though I have set the properties as so:-->
classname: PageTerm
graph: {"Page":{}}
sort: pagetitle
dir: ASC

I get this error [2017-02-23 18:30:32] (ERROR @ ///core/components/taxonomies/model/Base.php : 301) PHP warning: in_array() expects at least 2 parameters, 1 given

Has anyone found a solution?
