Can you upload plugin using ftp by steps:
1. Download your WordPress Plugin to your desktop.
2. If downloaded as a zip archive, extract the Plugin folder to your desktop.
3. Read through the “readme” file thoroughly to insure you follow the installation instructions.
4. With your FTP program, upload the Plugin folder to the wp-content/plugins folder in your WordPress directory online.
5. Go to Plugins screen and find the newly uploaded Plugin in the list.
6. Click Activate Plugin to activate it.
You can override template of plugin in your theme “x/dhvc-woocommerce-page/single-product.php”, then go to customize template add white background for page.
I go to check plugin on my localhost, it works. But if it does not work on your site, please go to theme setting and check if you enable woocommere product tabs config or not.
