Unexpected output incorrectly reported during plugin activation
|Reported by:||chmac||Owned by:|
When I activate the WP Mail SMTP plugin, I get the following error:
The plugin generated 194 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.
Other users have reported the same error with different numbers of characters. I've checked, double checked and checked again the plugin code, and I can't see anything outside of the PHP tags or any output functions called during activation. I think the issue has to lie somewhere else, unfortunately I've no idea where.
Plugin code is available here:
