Layout Designer Error 500

i have installed Xibo without ZeroMQ bindings for PHP. It works all but only the layout designer is not working. When i try to edit the design then the page /layout/designer/2 can’t load because a HTTP ERROR 500. Have anyone a solution?

Thanks for help.

What’s in the CMS log when that error occurs?

Nothing. The CMS Log have no information record about this problem.

In that case, you need to step through the Report Fault wizard. That will generate a file, however, additional logging should also be logged in the CMS logs. If you are able to isolate those logs that would be easiest.
