 * When I try to install this plugin to my website, it throws an error
 * > Fatal error: Cannot declare class ES_Widget, because the name is already in
   > use in wp-content/plugins/email-subscribers/lite/includes/classes/class-es-
   > widget.php on line 87
 * This class is coz of another plugin that I am running on my website. Is there
   a workaround with this, that you could provide?

 * Hi [@yennaellmangalore](https://wordpress.org/support/users/yennaellmangalore/),
 * We are really sorry for the delay in our response.
 * Can you tell us the name of another plugin that you are using? That would help
   us testing the issue at our end and fix it.

 * Hi there, I had this exact same error. In my case, it is a conflict with this
   plugin: [https://wordpress.org/plugins/easing-slider/](https://wordpress.org/plugins/easing-slider/)
 * Hope this helps 🙂
 * Thank you

 * Hi there,
 * We have tested the Email Subscribers plugin with the Easing Slider plugin.
 * Though the Easing Slider plugin is outdated, we couldn’t find any conflict between
   the two plugins. They both are working perfectly fine together.
 * Can you let us know where you are getting this error so we can test that as well
   on our end? You can also provide us the line number in Easing Slider plugin’s
   code files where this error is being triggered. That would help us to better 
   understand the issue.
 * Hope this helps you. Let us know if you have any further queries.
