Hello, I have concrete 5.6.0.1 installed by Bluehost. I worked with Silence theme and have deleted some older page versions. At this step I get a fatal error:

Fatal error: Call to a member function getBlockTypeHandle() on a non-object in /home1/websiuf0/public_html/concrete/core/libraries/block_view_template.php on line 41

This message I see now also when I try to connect with my website.
Does anyone can help me?

Thanks!
Dominic
