Hello there,
Sorry for the trouble. Let’s see how e can help.
This seems to be an issue unique to your installation because we have had no other reports of it and cannot replicate it to our local install of WordPress.
A theme or a plugin update might have caused a conflict with Easy Pricing Tables. We need to find out what is causing the issue in order to be able to address it.
To search for conflicts, please follow these steps.
1. First please deactivate all plugins except Easy Pricing Tables and see if the issue persists.
2. If the issue is resolved, reactivate your plugins one by one to see if the issue returns.
3. If no conflict is found among your plugins, try reverting to a default WP theme like ‘Twenty Sixteen’, or ‘Twenty Seventeen’, and see if the issue is resolved.

If you find a conflict with a plugin or theme, please let us know the name of the conflicting software and also try to contact the author of the conflicting software to see if they can fix it.
Thanks.
