Conflict with another plugin

Hi,

I was testing this plugin and it failed activation when I had another plugin Shortcode Maker (which is also programmed by you) activated. It’s showing following error:

Fatal error: Cannot redeclare showUpgradeNotification() (previously declared in C:\wamp\www\Divi\wp-content\plugins\shortcode-maker\shortcode-maker.php:363) in C:\wamp\www\Divi\wp-content\plugins\wp-post-front\wp-post-front.php on line 231

Deactivating the other plugin solved the issue. Doing the other way round generated same kind of issue.

Initially both the plugins are disabled. I have activated WP Post Front. It’s activated properly. Then I tried to activate Shortcode Maker. This time it generated same type of error message but with a different line number.

Fatal error: Cannot redeclare showUpgradeNotification() (previously declared in C:\wamp\www\Divi\wp-content\plugins\wp-post-front\wp-post-front.php:225) in C:\wamp\www\Divi\wp-content\plugins\shortcode-maker\shortcode-maker.php on line 369

For this reason, both the plugins can not be used at the same type.

Best regards.
