I have a opencart 2.1.0.1 . when i upload the zip file extension from extension installer from admin panel it gives me "invalid file type error".
unzip the plugin then compress it with the same name and add .ocmod.zip as extension worked for me.
extract your zip file, after extracting right click on the extracted folder and make it zip again and make sure to rename it with yourname.ocmod.zip i.e type ocmod before .zip and save and upload. hope this will help.
