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.
