Hello acelerawp,
Thank you for getting back to us. We didn’t know that you need to submit the issues on facebook instead.
We’ll look into it. Thank you
Hey there, this type of error comes from another plugin incorrectly using the filter that adds plugin links. The links should be an array, and another plugin must have been converting it to a string.
The other plugin should fix the issue, but I’ve also added a fix for this so that the incorrect filter usage won’t prompt an error in Stackable. It should be out in the next release.
