Few days ago I tried to update my wp-statistics plugin to 4.1
But after installation, the plugin inactivated completely and said that: the plugin has been inactivated due to serious problem!!! after that, I've tried to delete and re-install the plugin but the result was the same!
I've inactivated all other plugins but didn't work again?
I tried v. 4.2 but I have still can't active the plugin!
I really confused and I don't know what to do?
Please help me. Thanks
