warning: Invalid argument supplied for foreach() in includes/common.inc on line 1647

Can you report whether you have installeThis means basicad some extra modules? Can you reproduce this on a clean drupal with just views installed?

Im having the same problem even if I rebuild my taxonomies. Ive tried deleting all my taxonomies but the problem persists!
Thanks

Same problem, in DEV version too.

I changed the menu location for my taxonomy menu items, refreshed it and the problem was gone.

For me, Taxonomy menu works, if it is added to Navigation menu. If added to Primary menu, then this error occurs: warning: Invalid argument supplied for foreach() in C:\wamp\www\test.net\includes\menu.inc on line 743.

EDIT: For me it looks solved. Problem was in DHTML menu, I had to turn it off for Primary menu.

Good day I am trying to create and hierarchical select menu with vocabularies using taxonomy menu.
I have done exactly this with the example below however I keep getting this error any ideas maybe I have missed something. I have also tried ver. 2.9 and dev version but the error continues.

warning: Invalid argument supplied for foreach() in C:\wamp\www\ includes\common.inc on line 1647.

Okay I realised that you have to bring in the terms in to the vocabulary before enabling the vocabulary on the menu location. This solved the error:).

I started receiving this message after installing Taxonomy Menu Module. I cleared all caches. I removed all vocabularies.

And Now I am trying to start from scratch creating a new vocabulary. And this warning is displayed as soon as I click on the Add Vocabulary" tab.

same issue here

fixed after rebuilding it all manually

Hi all. I've encountered the exact same problem - can recreate every time: I install "taxonomy menu" and enable a certain vocabulary in primary links. This leads to "warning: Invalid argument supplied for foreach() in [path]/includes/menu.inc on line 743.". The only way to make this error disappear is to do the following in the DHTML menu module: Under "Menus without DHTML" make sure the "navigation" is ticked. Needless to say this is not what anyone who uses the DHTML menu module wants. It's 100% recreatable on my drupal installation (latest 6.20). Have tried both the 2.9 and 2.x dev version - same issue. Rebuild on submit option doesn't help.

This was fixed for me once I disabled the DHTML for taxonomy-menu in the DHTML configuations. Any patch available?

I get same error when managed Primary links menu using drag-n-drop. Error apeared after moving all submenu items from one parent item to another. I think the problem apears when parent menu item lost all sub items. The fix is to add new sub item and then delete it.

Fixed the same way. Thanks
