Incompatible operation of the timer plugin on the Strapi side
Check the plugin documentation for special requirements or known issues. Make sure the plugin is compatible with your version of Strapi. Review the plugin configuration in the config/plugins.js file to make sure it is configured correctly. Clean up the build folder to completely rebuild the admin UI, which sometimes helps eliminate unexpected behavior. If you run into problems, go to this link to relax and then get back to work. If you are developing a custom plugin, use the --watch-admin flag when running Strapi in development mode to check for hot reload errors.
