   and bad 😂) post.After an update of all plugins, we see that the plugin “Collect
   and Deliver Interface” prevents your plugin to be installed !!If we unactive “
   Collect and Deliver Interface”, we can install your plugin.Maybe I must see with“
   Collect and Deliver Interface” for this issue.But it is not normal the fact to
   activate “Collect and Deliver Interface” it deactivate your plugin !More for 
   information, unless you have a solution.Thanks,

 * Hello [@rguilbert](https://wordpress.org/support/users/rguilbert/),
 * Thank you for your message.
 * I have recreated your issue: [https://imgsh.net/i/5bb1a0804f](https://imgsh.net/i/5bb1a0804f),
   and I noticed that you’ve also tried to [contact ](https://wordpress.org/support/topic/conflit-plugin-ups/)
   the author of the “Collect and Deliver Interface” plugin. The problem is that
   this plugin adds a notice, and we don’t know why the author decided to block 
   us this way – we can’t change that on our end.
 * Unfortunately, I don’t see any other possibilities to contact them, such as an
   email address. The best we can do right now is monitor the thread (our developer
   left a comment there) and wait for the response.
 * I hope the problem will be resolved as soon as possible!
 * Best regards,
   Marta Borówka

 * Hello [@rguilbert](https://wordpress.org/support/users/rguilbert/),
 * I noticed that the author replied to you with a [solution ](https://wordpress.org/support/topic/conflit-plugin-ups/#post-18650163)
   that will be implemented in his plugin. Therefore, I am marking this thread as
   resolved.
