Now, I just reinstalled a fresh version of WordPress and on the front pages it says:
Notice: Trying to get property of non-object in /data/26/2/7/139/2496302/user/2733991/htdocs/pff_wordpress/wp-content/plugins/testimonials-widget/testimonials-widget.php on line 616

RSS Error: The data could not be converted to UTF-8. You MUST have either the iconv or mbstring extension installed. Upgrading to PHP 5.x (which includes iconv) is highly recommended.
What do you suggest? BTW, I was unable to uninstall the plugin, so renamed it.
Because of that, I think the WordPress app is trying to pull the data.
Thanks for your help.
