I love layouts. Once you get your head around how they work. But This is an annoying issue I am having frequently:
The "Main page content" block has incorrectly been positioned multiple times. This may indicate an incorrectly saved layout configuration.
This occurs after editing a block in my default admin layout, Update Block, then it throws this error. Save Layout throws the same error.
Workaround: Click Configure Layout, click Save Layout there, then it's happy...until next time.

Hmm, I've never seen that one before. I wonder if the admin default layout definition is somehow corrupted. This error should only happen if there is a block with the same uuid as another. Perhaps export and share the layout after saved?
I'm wondering also if perhaps a layout-related contrib module is messing things up? What contribs are you using?
Thanks mate, here is the layout:

Something definitely looks wrong in the "positions" subarray. Is this using a custom flexible layout template that you created? The weirdest part is the fact that there is an empty key under position, and the "default" content appears twice, under, "97bd4d56-184a-4e5a-8004-4b9df29f67d5--0" and under the empty key.
I'm not sure how this may have happened. I would try the following:
