Catchable fatal error: Object of class WP_Error could not be converted to string

Line 120 is actually

$top_cat = split(':',$cat_tree);

I’d suggest checking what $cat_tree is actually returning by dumping that string to the screen.

pls how do i do that…
am new to wordpress.
thanks

<?php // get parent category
$category = get_the_category();
$cat_tree = get_category_parents($category[0]->term_id, FALSE, ':', TRUE);
echo $cat_tree;
/*
$top_cat = split(':',$cat_tree);
$parentObj = get_category_by_slug($top_cat[0]);
$parent = $parentObj->name;
*/
?>

it is still showing the same error…
any other suggestion please.
thanks

[No bumping. If it’s that urgent, consider hiring someone.]

What output did you get for $cat_tree?

same out put…

In that case, you’re getting an error because $cat_tree is empty – which suggests that you’re trying to get the parents of a top-level category.

so how do i fix it now, sorry for the disturbance.

Well, it might help if you described what you’re using this code for and where.

when i check my uploaded files via my mobile theme, there are there but when i check them via my desk to theme i get his same error either am logged in or not.
