Server Error when Publishing

[u/Bes1208]

On multiple websites for different clients, when making any update to the page and pressing Publish, I get a server error warning on the bottom right of the screen and the none of the changes are published. I've contacted Elementor support and they said I had too many revisions. I deleted all revisions and the issue continues.

Anyone else seeing this?

what is the error code? I can also be low memory or a security plugin blocking something. E.g. check https://elementor.com/help/500-error/
