Using a Confluence evaluation license, the Visibility plugin gives a license error. I have tried uninstalling and re-installing the plugin through Confluence but there is no change. I am testing Confluence 5.9.6 and Visibility 3.0.1.
The error message was displayed on the page in a red box with the same text from this subject (The license could not be verified: There is no license certificate installed for CustomWare Visibility Plugin for Confluence.), in place of the actual content that should have been displayed.
I don't get the error now, I had to download a new license file and install it for this plugin. But what I don't understand is why what was necessary if the plugin was uninstalled and re-installed?
