As you can see on my website, there is this text that appears on the pages, there are apparent notice. "Notice: Trying to get property of non-object in /home/guillaum/public_html/ndxzstudio/lib/cache.php on line 75" See : guillaumeadjutorprovost.com/index.php/project/providence/. Is there a way to remove this thing (it appears on every pages) Thank you for the update
