If you get this message, you are either trying to post from a local website installation or have recently moved your WordPress or changed your hosting service.
The social networks do not allow postings from local installations. Please make sure that your website can be reached by anyone and that no European IP addresses are blocked.
If you recently changed your hosting service, server or domain or moved your WordPress, please uninstall Blog2Social in the WordPress plugins section and re-install it again to make sure the installation is valid.
To do this, click on "Plugins" in your WordPress backend and deactivate Blog2Social. Please do NOT check the box saying „Delete scheduled posts“, otherwise your planning will be deleted. Deactivate and then delete the plugin.
Then click on „Plugins“ -> „Add new“ and install the latest version of Blog2Social and activate it.
