Good afternoon,
In "Confluence 7.4.0", appear the error message:
"Balsamiq Wireframes EULA Violation. This version of Balsamiq Wireframes for Confluence is more recent than what your license allows. Please contact your Confluence administrator so that they can purchase a maintenance license and continue to edit your project."
This situation occurs when I go to Confluence an click in "edit", + sign, "Other macros" an then select "Wireframe".
Additional information: Local version "Balsamiq Wireframes 4.4.6"
Best regards.
