Permalink edit results in White Screen error

I changed the permalink structure from the default format to the "Post" format in the Dashboard and now all pages of the website are showing the white page of death. When I changed the permalinks back to default it didn't do anything. Help?

Hello,
The problem is caused by changes in new version of WordPress, you have to wait for new version of plugins and our theme (will be available today or tommorow), as a temporary solution, try to disable all of your plugins.

Thanks for the reply! I updated the theme and plugins (using the second method in this post https://www.gavick.com/documentation/wordpress/guide/theme-upgrade, but to no avail. The white screen error still persists. Help?

Please check also this article:

and let me know which errors/warnings do you have.

I found out what the issue was. I had the Buddypress plugins disabled, which is perfectly fine as long as the permalinks are set to default. Changing the permalinks to "Post" apparently causes some kind of collapse with the theme if the Buddypress plugins aren't active. Switching those plugins back to active caused everything to work again.
