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.
