Hi @arafatjamil01,
How did you install the plugin? Was it done via FTP or through the dashboard under Plugins?
Could you please try going to your site’s dashboard > Plugins > Add New > search for Square > then upload and activate from there?
Thanks!
Thank you for your reply.
I tried exactly the way you just wrote. Then I downloaded the plugin externally and upload again. The result is same. Shows the error.

Hi @arafatjamil01,
Thanks for testing that. Could you please check that the folder structure is correct in FTP? Here’s a post that helps with a possible fix: https://chattymango.com/how-fix-wordpress-error-plugin-not-valid-header/
We haven’t heard back from you in a while, so I’ll mark this thread as resolved now. If you have some more questions, feel free to start a new one.
Cheers!
