I wrote a custom plugin for my own sites, and I called the filename 'myplugins.php'. WordPress seems to think that this is another plugin from the plugin directory that uses 'myplugins.php' as a filename, and is giving me a message saying that an upgrade is available. Because this is referenced in lots of other code I can't change the filename.
How can I have this plugin be unique from WordPress's perspective? Is there a header I can add?
