I found this error often in my error, how did I get this?
[Apr 18 00:49:11 2015] [Customer] 188.165.15.227] Mod_FKGid: STARR: Note PHP: Optional: Tabletections :: $ Category_parent_id in * domains / twr-trading.nl/public_html/components / com_virtuemart / views / category / view.html.php on page 162
its just a notice but did u copy/paste this? it makes very little sense
the only instance of Category_parent_id in that file is line 662
maybe it needs
if ($cat and !empty($cat->category_parent_id) and $this->categoryId != $cat->category_parent_id) {
to
if ($cat and isset($cat->category_parent_id) and !empty($cat->category_parent_id) and $this->categoryId != $cat->category_parent_id) {
or similar
