I don’t know if there is anyone of this plug-ins that i must delete, but i think that if i delete all this plugins, the problem would be still there.

Yeah, i changed the plugins folder name to plugins.old but now al the plugins are not visible in WordPress because i changed the name to .old.

So as you can see on this image: http://www.imgdumper.nl/uploads8/5491790eda2f5/5491790ec2fe7-Schermafbeelding_2014-12-17_om_13.37.16.png , the WordPress post is still bad.

There is one thing that i know now, and that is that all my plug-ins aren’t the problem. So there must be something else.

I have still all the plug-ins off.
