 * Hi
 * A couple of months ago I had an issue with a web site whereby when I’m in the
   dashboard and go to select plugins I get the screen below where all the plugins
   deactivate with the error “The plugin does not have a valid header” see [Screenshot](https://lh3.googleusercontent.com/-6Bu-mrr9jQI/Vg0ZzLAIznI/AAAAAAABOaI/FwkATmSAnIU/s912-Ic42/Screenshot%252520%25252860%252529.png)
 * I have been able to restore the site from backups.
 * At the time I deleted and restored all the plugins and everything seemed to be
   running OK but the same issue has now returned. I have also run database checks
   and repairs.
 * As long as I don’t attempt to access plugins all works fine, but obviously not
   practical going forward.
 * Any advice would be greatly appreciated.
 * Many thanks
 * Jim…
