Hello Nour,

Thank you for reaching out to us.

Issues like this usually occur when there is a conflict either with the theme currently active on your website, or another plugin you have installed.

Can you please change the theme and see if the issue is resolved? If not, then please deactivate all other plugins except for our plugin, refresh the page where the issue is, and see if it is resolved (it should be). If it is, then start activating other plugins one by one, and after each activation refresh the page to see if the issue reoccurred. Once it does reoccur, you will have found the plugin causing the issue.

It also could be a cache issue.

Please deactivate Amelia, clear the cache, activate Amelia, and clear the cache again. 

You can clear the cache with the plugin "W3 Total Cache", "LightSpeed Cache" or any other, and also clear your browser cache and cookies.

Let us know if it helps, please.

Look forward to your reply.

Have a nice day!
