Is it a bug?

What needs to use this
div tag by default you do then just change the id or class only

That happens because the plugin scripts are loaded after the theme scripts.

Can you tell me what theme are you using?

Thanks for the bug report.

Tessaract Theme which could be downloaded here

So How am I gonna fix this,
Is it different in previous version.
if it is, could you send me the first version thank you for your help ??

You can use the old version while I try to fix this problem. Here is the first version:

https://github.com/igpremuo/hover-image-button/archive/master.zip

Copy the hover-image-button folder in to the /wp-content/plugins directory`.

A new version of the plugin has been released and the bug has been solved, you can update to the last version.

Wow! that’s cool Thank you so much
