 * Dear Support,
 * I am contacting you following the new release of SG Optimizer and cache flush.
 * I have contacted you some days ago because I have a plugin (Userlike) that is
   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.
 * Following my ticket you released a new SG Optimizer version. I was happy to upgrade
   the SG Optimizer plugin and and finally 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.
 * Thank you in advance, any help is appreciated.
 * Fabio.

 * Please, contact your other plugin developers. They are modifying content without
   triggering the proper hooks or something else is cached on their end. If you 
   purge the cache on SGO and manually purge it on Cloudflare account there is nothing
   more to do. SGO is working just fine, please check your plugin and get a developer
   for more detailed assistance. If they detect any issue with SGO, please provide
   us with exact information since so far everything is working as supposed.
