JRoute giving wrong path for new menu items

Question

Since a recent point in time (I believe since I installed the paid version of HikaShop) JRoute gives the wrong SEF url for all new menu items and 404 errors.

For example JRoute::_('index.php?Itemid=<OLD MENU ITEMID>') returns the correct url path /<MENU ITEM ALIAS> (and results in NO 404 errors)...

... but JRoute::_('index.php?Itemid=<NEW MENU ITEMID>') returns the wrong url path /Products/<MENU ITEM ALIAS (and results in 404 errors)

The behaviour can be seen for all new menu items whether or not using the HikaShop component - so it may be nothing to do with HikaShop.

I have checked the output of router.php for HikaShop and it appears to be working okay

I would like to debug JRoute further but in Joomla 3.5 cannot find where this class is defined. Joomla 1.6 and 1.7 APIs refer to methods.php, but I cannot find this file for 3.5 API

So at a loss as to how to proceed... Until I get this sorted the site is unusable...

Answer 1

Turned out to be a Joomla problem, which has long history: new menu item - wrong address . After rebuilding the menu items the issue with /Products/ in the path was resolved.
