 * After I activated the plugin, it gave me the following message:
 * The plugin generated 1 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.
 * I then go the home page of my website and it generates this message in the header
   that is visible briefly but extends the header length:
 * Warning: : Cannot modify header information – headers already sent by (output
   started at /home/dh_jyzt5z/sandiamesa.com/wp-content/plugins/blog-mechanics-theme-
   gallery/2jgallery.php:1) in on line 68.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fheader-issue-30%2F%3Foutput_format%3Dmd&locale=en_US)
