Hi guys,

I'm using OC  2.1.0.1 with custom theme. After I installed NotifyWhenAvailable extension, I cannot access to product detail page. The system is shown "This site can’t be reached" with ERR_CONTENT_DECODING_FAILED.

I found the problem is loading language file: $this->language->load('module/notifywhenavailable'). I skipped and the product detail page is working now. But Nothing changes and there is no notify button. What should I do now?

Thank all.
