 * This has been happening for a while. I’m trying to reactivate after it locked
   up my site (two updates since then), but I still get this error message:
    Fatal
   error: Cannot redeclare class scssc in /home/piggys7/public_html/wp-content/plugins/
   maxbuttons/classes/scssphp/classmap.php on line 20
 * Is there anything I can do about this?

 * Hi,
 * Yes, please check if you are not running two versions of the plugin at the same
   time. That usually causes this error.

 * How can I check for two versions without deleting and re-installing? I worked
   hard to get the buttons PERFECT. (And while they worked, the plugin was 5-star
   and did exactly what I needed.) Is there a way to check without starting over?

 * You can check this in the plugins section of WordPress. There should be only 
   one version of Maxbuttons activate there.

 * Oh no, there’s just one version listed, and it’s the latest version. It’s deactivated
   at the moment because WP won’t let me activate it – says it can’t because it 
   caused a fatal error, giving the specifics as above.

 * Usually there is a line after something like ‘scss already declared in xxxxxx’,
   could you check if you can see that and post it here? In a very unlikely event,
   the plugin is conflicting with another.
