 * Doesn´t hurt the front end of my website, but it´s a constant error.
 * Anyone any idea how to solve this (without being to technical).

 * It appears in the admin area. In the plugin section and the update section. It’s
   the only place where it appears. It appears after every plugin, WordPress or 
   theme update. Also after new plugin install. Will send screenshot later.

 * I have the same problem. And by the way, my website isn’t working anymore because
   of that. I tried to open it in a new tab, new window, new browser, new computer…
   And always the blank screen. I even can’t access my Admin panel anymore – that’s
   to say, my website is completely broken. And of course, I can’t wait for the 
   next update as you said above. What should I do in this case? Thank you.
 * Edit: profmatheus.com is my (now broken and not accessible) website.
