Update failed.

Thanks for the great plugin. When I try to update the plugin, it says update due to inconsistent file permissions. Here is the screenshot, I have translated the plugin. Here is the error message “Update Failed: The update could not be installed because we were not able to copy some files. This is usually to inconsistent file permissions”

Would be great if you can help me with same.

Before this when placing ad it fails to go to step 2 i.e after entering ad details it failed to go to step 2.
