 * Hi,
    After activating your pluign my website crashes with critical error “Warning:
   require_once(/wp-content/plugins/sidebars-blocks/sidebarblock/sidebarblock.php):
   failed to open stream: No such file or directory in /wp-content/plugins/sidebars-
   blocks/gpls-ssig-widgets-in-gutenberg.php on line 148
 * PS! If someone tries to install your plugin and go to Plugins >> Add new and 
   search for “Sidebars Gutenberg Blocks” then nothing comes up. If I search by 
   author “GrandPlugins” then it comes up.
    So, maybe you can do something about
   it, otherwise no-one can find your useful plugin.

 * Thanks for the heads up. It should be fixed now. sorry about that.
 * I don’t know about the search part. maybe because It’s a new one.
