 * Dear Support,
 * I am contacting you because I am experiencing a problem with the plugin, in particular
   purging the cache.
 * I have another plugin (Userlike) that is properly loaded based on a serial key
   added in the plugin setting. Following an update of the userlike plugin i had
   to replace the serial key. For some reasons SG Optimizer keep loading Userlike
   with the old serial key. It looks like that SG takes the old serial key from 
   the cache while combining JS.
 * I am puzzled because I have already purged the cache of SG Optimizer by flushing
   the cache Level 1, 2 and 3. I have also purged the cache of Cloudflare. Still,
   SG Optimizer loads the old key and prevents userlike to work properly.
    When 
   I disable SG Optimizer the correct userlike key is loaded and the plugin works
   fine. I concluded that there is something wrong with SG Optimizer.
 * Could you please help me to solve the issue?
 * Fabio.

 * Dear Stanimir,
 * Thank you for your message.
 * I was happy to upgrade the plugin and and solve the problem however, I have realized
   that the new release does not solve the issue. The old key is still passed although
   i flushed the cache level 1,2 and 3 and cloudflare.
    Could you please verify 
   the situation, I believe that something is still not working fine with SG Optimizer.
 * Thanks.
 * Fabio.
