“Unexpected output during activation” error #6
Description
Using version 1.0.1 of the plugin on WordPress 5.9.4 and 6.0.2 with WP_DEBUG set to true.
When activating the plugin, the following message appears at the top of the “Plugins” page:
The plugin generated 599 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.
Setting WP_DEBUG to false eliminates the onscreen message of course, but the reporting of the “unexpected output” is rather odd.
