Hi Patrik
Thanks for your message. This error comes from the Related Posts Addon in an older version of SiteOrigin Premium. Versions 1.64.0 to 1.68.1 build the addon settings from the Blog Widget without first checking that the Blog Widget is active. When the Blog Widget is turned off, the Premium Addons page stops with this error. SiteOrigin Premium 1.69.0 added that check.
I think either of these steps might resolve it:
1. Update SiteOrigin Premium at Plugins > Installed Plugins. The current version is 1.80.0. Updates need an active SiteOrigin Premium license. If your license is active but no update shows there, you can download the latest version from your SiteOrigin dashboard and upload it at Plugins > Add New Plugin > Upload Plugin.
2. Activate the Blog Widget at Plugins > SiteOrigin Widgets. Find Blog in the list and click Activate. The Premium Addons page should then load again.
The first step is the lasting fix, because it keeps the Addons page working even when the Blog Widget is off.
If your license is active, email is the better channel for SiteOrigin Premium support. You can find our support email on the Contact page.
Kind regards,
Andrew
