 * In the past 3 days my WordPress site running WP Super Cache 1.5.9 occasionally
   gives the following error in both Firefox and Chrome (haven’t tried Edge)
    CONTENT
   ENCODING ERROR The page you are trying to view cannot be shown because it uses
   an invalid or unsupported form of compression. Please contact the website owners
   to inform them of this problem.
 * I turned off Compression in WP Super Cache and the problem goes away. When I 
   turn compression back on the problem returns.
    Is this a bug?

 * Do you have compression enabled in PHP or Apache?

 * Compression is not enabled in either one.

 * The reason it is not enabled in either place is because it causes errors. I’d
   like to enable it but I’ve given up.
