I am getting the white screen of death on my site only when trying to access the Blog page. If I switch to a different theme like Twenty Seventeen the blog shows up correctly but in Shapely it does not. If I change my homepage from static to show latest posts then the homepage gives me the white screen of death.
I tried deactivating my plugins and it didn’t seem to solve the problem.
If that didn’t fix the issue, please turn on WP_DEBUG WP DEBUG « WordPress Codex so that it will display the error on the white screen, so that we can fix it accordingly.
What i ee in your messages is WordPress related problems, i cant see anything related to the theme, its best to research such question in the WordPress support or in the internet
please get in touch with your hosting provider about this question, your hosting environment can be configured only with your hosting provider
