Also sent you a contact. Just purchased and it looks like your .zip file for both the plugin and the licensing is not formatted correctly.
This is what I get when I try to install…
Installing Plugin from uploaded file: easy-bootstrap-shortcode-pro.zip
Unpacking the packageā¦
The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Invalid End of Central Dir Record size : 14
And trying to open the .zip file locally results in creating yet another compressed .zip file.
Please fix and advise.
