 * This may be a plugin or theme conflict. Please attempt to disable all plugins,
   and use one of the default (Twenty*) themes. If the problem goes away, enable
   them one by one to identify the source of your troubles.
 * If you can install plugins, install and activate “Health Check”: [https://wordpress.org/plugins/health-check/](https://wordpress.org/plugins/health-check/)
   
   It will add some additional feature under create a new menu position Tools > 
   Site Health. On its troubleshooting tab, you can Enable Troubleshooting Mode.
   This will disable all plugins, switch to a standard WordPress theme (if available),
   allow you to turn your plugins on and off and switch between themes, **without
   affecting normal visitors to your site**. This allows you to test for various
   compatibility issues. There’s a more detailed description about how to use the
   Health Check plugin and its Troubleshooting Mode at [https://make.wordpress.org/support/handbook/appendix/troubleshooting-using-the-health-check/](https://make.wordpress.org/support/handbook/appendix/troubleshooting-using-the-health-check/)

   seo” old version plugin and the problem with the titles, images and description
   of plugins i can’t see [https://snipboard.io/cEMpDi.jpg](https://snipboard.io/cEMpDi.jpg)
