I turned on error messaging in Joomla and the code appearing after the installation of K2 v 2.4.1 is attached in the file show-errors.txt. In the K2-controlpanel.txt you'll find the code generated when displaying K2 control panel after installation. I also attach the source code of the generated web page when returning to the dummy site URL after the installation: source.txt. Sorry for the Swedish sentences, but I hope you may find what you are looking for.
The backend of the dummy website works after upgrading K2, it's the frontend that fails.
I not quite sure what kind of information you need. If the attached files do not hold useful information for you, please advice on what more material you need.

Just a thought: could SEF have anything to do with this problem? Joomla's core SEF is turned on in the original website.

Hi. You need to turn error reporting to maximum to see the error. This can be done under Joomla! global configuration. Also try disabling some modules and plugins in order to find where the conflict is. Thanks.

Sorry, I missed that, only turned on debug...
Now I have turned error reports to maximum. What URL:s do you want me to check? When I visit the frontend URL I still see a blank page.

A breakthrough! I started to disable some modules and voilá: the website showed up when I disabled all copies of mod_k2_content. When I turned them on one by one it was only one of the copies that created the problem. It doesn't matter if I use default or an own sub-template.

Does this give you a hint? I upgraded from v 2.2.

Since it is not your template issue try to tweak some settings in the specific module in order to find out what's causing this. Please let us know. Thanks.

Hi again,
I tried as you suggested and changed the settings of this instance (copy) of the module. I also tried to create new copies of the module. This happened:

- It seems that the troubles occur when Select specific items is chosen AND there are one or more articles added (the website works if there's no article added although Select specific items is chosen).

- I also changed another (working) instance of the module from Retrieve items from categories to Select specific items and this instance (copy) continued to work even after some articles were added.

-When I create a new instance (copy) of the module with the setting Select specific items / article added the webpage fails. Removing the added article makes the page work again.

- When I changed the new instance from Select specific items to Retrieve items from categories the webpage fails.

OK. There you have some cases. Please let me know if you need more information.

Hi. Your feedback is great but still i cannot reproduce the bug. What other extensions are you using? Also, did you managed to see the actual error or are you getting still the blank page?

Hi,
There's no error message at the websites frontend, just a blank page.

As soon as I pick an article for the Select specific items feature, the webpage goes blank. When I remove the selected page it turns on again. Also, if I create a new instance of the module in question the webpage goes blank when I select any specific item.
