I am having the same issue today. We just moved a clients site over to SG and installed the plug-in today at the recommendation of several people. Can’t active it as we get the same error:
Fatal error: Can’t use method return value in write context in /home/gotopsi8/public_html/wikitest/wp-content/plugins/sg-cachepress/core/Admin/Admin.php on line 25

Thanks
