Claude

I have been able to find your account.

You whitelisted: https://www.tech.graphicline.co.za
Your blog is however at: tech.graphicline.co.za (no www)

I whitelisted tech.graphicline.co.za, the buttons should now be displayed.

Hi Mike, to increase the security of the plugin, it will only work with domains that have been whitelisted.

Please login to your oneall account, click on Site Configuration, select your site and then Security Settings.

The domain of you blog must be in this list, otherwise it will not work.

Feel free to contact us if you need any further assistance.

Hello,

the plugin does not work without CURL being installed.

If your PHP has CURL disabled, we trigger this error upon activation to prevent you from installing a plugin that won’t work.

Most of the hosting companies have this module already enabled.
How to enable CURL:
