Hello,
Thanks for reaching out to us.
As this occurred right after an update, it is likely a conflict with your theme or plugins.
Please follow these steps, and let me know if it solves the issue:
– Deactivate all of your plugins except Elementor. If this solves the problem, gradually activate your plugins one by one, until you spot the problematic plugin.
– Switch your WordPress theme to WordPress TwentySixteen (or other default WordPress theme) temporarily – and see if it solves your error.
I hope this information helps.
Best Regards,
