An error has occured after I changed wordpress url

Hi,
I changed my wordpress url and now when using the testimonials i get the following error: Warning: move_uploaded_file(/xxx/original/phanny-chan-convergys.jpg) [function.move-uploaded-file]: failed to open stream: No such file or directory in /xxx/wp-content/plugins/fv-testimonials/model/image-class.php on line 740Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move ‘/data/20/tmp_new/phpMvDip1′ to ‘/xxx/original/phanny-chan-convergys.jpg’ in /xxx/wp-content/plugins/fv-testimonials/model/image-class.php on line 740and Error while moving uploaded file to it’s new location: ‘/xxx/original/phanny-chan-convergys.jpg’ Everything else was updated except from images !Testimonial updated if i change my url back to include /wpadmin by default it works without issue. I have deleted the plugin and reinstalled the plugin but still not working. Please advise what is causing this error asap as this is effecting my site.
thanks
