I have a bizarre problem with your plugin.
I am using it for the past couple of weeks and it has been working fine.
Suddenly from today morning it has stopped working.
I haven't done any modifications in my website or activated or deleted any plugin.
The error shows up is that ...............
Your CSV file cannot be processed. It may contains wrong delimiter or please choose the correct delimiter.
1. Your CSV should contain "," or ";" as delimiters.
2. In CSV, tags should be seperated by "," to import mutiple tags and categories should be seperated by "|" to import multiple categories.
This is happening even with your sample file and files I have earlier uploaded successfully using the plugin.
