Message Log Warning Prompts SPAM

How am I supposed to prevent this from happening please?

It’s not a warning, it’s an error. Best thing is to get rid of the problem.

Alright it is an error. But how do I prevent those popups from spawning without disappearing. They keep stacking up until they are closed manually, even though all the errors are fixed.

The only way is to fix the errors and then click them away, I’m afraid.
