I am also having this error
Parse error: syntax error, unexpected T_OBJECT_OPERATOR in /homepages/5/d268540004/htdocs/testing/wp-content/plugins/wp-eMember/auth.php on line 156
Please advise, and is it possible to just post the solution here? Since there are multiple users with the same issue it might save you customer service time to just have a single solution everyone can point to.
