i tried to reload the plugin but its said unknow siple at the end of the file how to fix THAT ??!

What exactly does it say?

That error means that the file was unreadable by the compiler; generally caused by the method it was uploaded that changed the encoding. If using a tool such as FileZilla, try setting the mode to Binary when uploading rather than Auto.

ohh oky thank u so much but should i set it to binary always is that better for plugins
