Remove the code shown in Red then save the plugin, afterwards save the plugin display order (when it shows list of plugins scroll to bottom and hit save).
I removed the code and my forum working fine. After some time forum start to redirect myfilestore.com. I disabled "Auto Check Remember Me & Rules Boxes" product and forum not redirect. Today i noticed that forum again start to redirect myfilestore, when i disable "Chrome Browser Notice by BOP5" product and forum not redirect. After few minutes, i enabled both products "Auto Check Remember Me & Rules Boxes" and "Chrome Browser Notice by BOP5" but forum working fine.
I could not find malicious code in both product.
Why forum again redirect to myfilestore? any suggestion?
