Hope you’re doing well. We’ve investigated your query with our DEV team, and it appears that the issue you’re encountering is not occurring from our plugin. If the issue were related to EmbedPress, it should include an **EmbedPress URL**. Please recheck by deactivating EmbedPress. If the issue persists, it might be a problem with another third-party plugin. **However, if the issue goes away, you can confirm that the problem is with EmbedPress.**Please let us know the update after the test.Thank you. * Thread Starter [nanny7](https://wordpress.org/support/users/nanny7/) * (@nanny7) * [2 years, 5 months ago](https://wordpress.org/support/topic/uncaught-referenceerror-viewpreview-is-not-defined/#post-17272935) * Hi it is this url [embedpress]https://www.australianfoundryinstitute.com.au/vooneboa/ JohnCampbell-Bifilms-for-Beginners.pptx[/embedpress] * When I disable the plugin the error goes away and when I enable it again the error comes back. * Plugin Support [Ashikur Rahman](https://wordpress.org/support/users/ashikurwp/) * (@ashikurwp) * [2 years, 5 months ago](https://wordpress.org/support/topic/uncaught-referenceerror-viewpreview-is-not-defined/#post-17274189) * Hi [@nanny7](https://wordpress.org/support/users/nanny7/), * Greetings.

Thanks for providing the details. The error you mentioned is not actually an error. We’ve used that hook to identify whether the embedded content is working perfectly or not. You can simply ignore it; it won’t cause any issues to your site. However, we will try to improve that soon as well.Thank you.
