My attempt is quite similar to yours. Your here:
[[!getPage?
&elementClass=`modSnippet`
&element=`getResources`
&showHidden=`1`
&parents=`4`
&tpl=`page-obits`
&includeTVs=`1`
&processTVs=`1`
&pageLimit=`5`
&pageNavVar=`page.nav`
]]
Mine here:
[[!getPage?
&elementClass=`modSnippet`
&element=`getResources`
&parents=`12`
&depth=`0`
&limit=`3`
&pageVarKey=`page`
&sortbyTV=`date`
&sortdirTV=`ASC`
&showHidden=`true`
&includeTVs=`1`
&tpl=`newsRowTpl`
&pageFirstTpl = `<li class="control"><a[[+classes]][[+title]] href="[[+href]]">Erste</a></li>`
&pageLastTpl = `<li class="control"><a[[+classes]][[+title]] href="[[+href]]">Letzte</a></li>`
]]
<div class="paging">
<ul class="pagination">
[[!+page.nav]]
</ul>
</div>
Some other values and I don't process TV's...
Did you try with &limit=`1`? And empty the cache after that?
