Solved Trouble with preview

Hello (again),

I have little trouble with the preview function. When users click on it nothing happens. I have tried to use debug mode but I dont get any message there and can't provide more details than below. Can you help me out? Could it be some conflicting components/extensions I use?

Here is report:

Could it be some conflicting components/extensions I use?

Yes, that's possible. You can test it if you disable third party plugins. When the error is gone, then enable the plugins one by one so you can find the cause. But try it first, whether the error also with the Kunena template Crypsis exists.

Thanks, now it is fixed. It was ”menu styles”, ”Gupta”. Are there some nice compatible drop down menu extensions you recommend?
