 * Hello,
 * Thank you for creating this plugin.
 * When I try to activate the plugin on certain installs of WP, I receive the following
   error.
 * I have received this error on my localhost and on a live host. But I have also
   been able to run the plugin on live host as well.
 * I’m unsure where the issue is, or what the difference is between the installs
   that is throwing the error. I’m not receiving this type of error with any other
   plugins, where it will or wont work on some installs of WP.
 * `Fatal error: Call to undefined function cmb_get_option() in [path]\wp-content\
   plugins\google-maps-builder\admin\class-wordpress-google-maps-settings.php on
   line 421`
 * Any ideas or tips would be appreciated.
 * Thanks,
 * [https://wordpress.org/plugins/google-maps-builder/](https://wordpress.org/plugins/google-maps-builder/)

 * I was having the same issue. I ended up downloading one of the most recently 
   changed branches on Github, installed it, and it worked for me. Looking at the
   diff, it looks like most (if not all) references to cmb have been changed to 
   cmb2 (i.e. cmb2_get_option). Hope this helps.
