Widgets show below Content

Hi Folks,

Since i updated Wordpress and Activello i don´t know who ist “guilty” why my Blog does not work anymore how he should. On the Detail Pages the Widget Area shows below the Content. I was able to find out that it has something to do with the content-single.php. I added some wrong code like “eregwtrwqrhgrsqgfsqf” and this Code showed up, but after changing this File to Colorlibs original File, the Problem still existed. And it also exists with a completely new installed Theme, not by Colorlib. So it guess there is probably some Problem with Wordpress. But now my Question, since i am not a php Crack. On which File of the original Wordpress Code is Activellos content-single.php based?

Kind Regards and many Thanks in Advance
GT
