For my wife's business I manage a website that uses #WordPress in the background. The pages are made with #elementor which is a powerful #WYSIWYG online-editor to create pretty nice designs.

Over the years the site constantly grew, gotten some replacements, etc. Every update has worked fine so far, until yesterday.

When I hit the "Publish" button in Elementor, an error showed up for a couple of seconds: server error (error 500).

The HUH? and the A-HA! in my blog.

@sterndata I did all this. WP_DEBUG showed no error. I expected a real PHP fatal error, which would have explained the HTTP 500 error. If you read the full blog post, then you see what the issue was.
@sterndata @ck Just read the blog post - so is Elementor revisions the same as WordPress post revisions or Elementor has its own revisions system? This is something I will look into as we use Elementor currently
@dalereardon @sterndata I am not a WordPress or Elementor expert, but what from what I understand the revisions apply to both.
