 * Hi [@rufmedia](https://wordpress.org/support/users/rufmedia/),
 * Thanks for contacting us,
 * We have checked the code and we are unable to find the issue in the code. In 
   the includes/Main.php on line #66, there is no LMFWC_VERSION constant variable
   declaration for reference check the screenshot: [screenshot](https://www.awesomescreenshot.com/image/15184335?key=84de47a993d1bf12926d0d37e14bff0a).
 * Also, can you let us know the page where you are getting this notice?
 * Thanks

 * Hi [@rufmedia](https://wordpress.org/support/users/rufmedia/),
 * We are still unable to reproduce the notices using the Query Monitor plugin.
