Compatability problems

When I activate the weather underground plugin and place a widget in the right side column the Home page is not displayed when opening the website. I have tried both the blog front page and the static front page but both behave the same. If I disable weather underground my front page behaves normally and opens on site access.

Using Colormag-Pro theme but problem occurs with other themes tested. I also deactivated all other plugins installed to test if the problem was an interaction but activating the weather plugin by itself causes the issue
