Fantastic! Thank you. It took a while to figure out which one it was and how the tool worked. But eventually I found out it was the Elementor plugin. So removed it and it all works smoothly now.
Thank you ThemeSumo, it’s correct I have three domains on this IP. They are all hosted by the same provider and are part of the same hosting package. I will contact my provider and see if he can fix this for me.
