 * Hi [@shrimp2t](https://wordpress.org/support/users/shrimp2t/),
 * I have tested Gutenberg with Custom Sidebars on my end but I’m afraid that I 
   can’t replicate this issue.
    I did experience an issue with the initial activation
   until the Custom Sidebars message is dismissed and I will report this to our 
   devs.
 * But that still didn’t fire up any errors and after dismissing it from Widgets
   panel I was able to use Gutenberg editor without any issues.
    Can you tell me
   which blocks you have on your page so I can test with a similar setup and see
   if it could be related to the specific block?
 * Cheers,
    Predrag

   declared in wp-content/plugins/custom-sidebars/views/metabox.php:29) in wp-content/
   plugins/custom-sidebars/views/metabox.php on line 29`

 * Hello [@thinkrameez](https://wordpress.org/support/users/thinkrameez/)
 * Hope you are doing well!
 * Thank you for posting in this thread, however, this topic is closed for the original
   author of this thread. Please open a new thread in our support forums.
 * I could not replicate this issue on y end, with latest plugin version and WordPress
   5.0.3. Before posting a new thread, please make sure all plugins are up to date.
   Run a quick check for conflict with another plugin. Deactivate all plugins besides
   the Custom Sidebars and see if you can replicate the same. Switch to a default
   theme to see if there is a conflict with a theme.
 * Thank you,
 * Kind regards,
    Nastia
