I have been having trouble with the plugin keep deactivating and this error:
The plugin ewww-image-optimizer/ewww-image-optimizer.php has been
deactivated due to an error: Plugin file does not exist.
Last time I had the error I removed the plugin using FTP and then reuploaded a new copy about three days ago. Everything was working fine and I updated some other plugins and then the error comes up and EWWW is nowhere to be found. The files are all there in the Plugin directory though but it is not showing in the list of plugins.
Therefore the only way I can get the plugin back is to delete and reupload it (the only way I know how without digging around in the database anyway).
Any ideas what might be causing this behaviour. If I upload again teh plugin will work again until it suddenly decides to go missing again. Help please.
