Read more on main page causes 500 view not found

Hello, please help me figure out how to fix the issue.
I've got 100% the same issue like here
I'm using BlueBee_Quickstart_v2.0.0 is it still live? I've downloaded the latest installation package (without quickstart) and can see it differs, e.g. components/com_solidres/controller.php has a different structure.
I tried to apply you recommendation in the topic mentioned above, and it helps to resolve 500 issue, but instead it's produced another one. Now no data is displayed on this page - just header and footer parts of the site plus availability search form.
Sorry for so unstructered question, I would just appreciate for any hint.
I'd like to start with finding out wether I've installed the latest version or not. where can I find it?
