Hi there,
Firstly I\'d like to congratulate you on a fantastic plugin in WP-Smart-Sort. I\'m hoping the error I\'m experiencing is relatively easy to fix.
On our site travelHorizonStyle.com.au, when I choose a country, then click on Multiple Category Selection Widget\'s [Search] button I get the following error:
Catchable fatal error: Object of class WP_Error could not be converted to string in /home/tra47941/public_html/wp-content/plugins/wp-smart-sort/wp-smart-sort.php on line 136
Line 136 in your plugin is:
if (\"/\" != substr($url, -1)) {
$url = $url . \"/\";
So I\'m assuming that you are checking for a trailing \"/\" but the url is not being passed to your function. If I comment out these lines, of course i get an error way further down on line 912.
Please let me do some testing for you to try to get these 2 great plugins to work together.
