Hey, your file does not have its required format, that’s the reason why it cannot be imported. It must look like this:
1|tag name|related word;foo;lorem ipsum
2|another tag|dolor sit;amet
3|random keyword|related words
The ID is not important but just make sure that it is unique for every row.
You can download a sample backup file if you have created some tags via the plugin already.
I’ll add your suggestions to my to-do list. The problem is that I have a lots of other ideas on the list so it may take some time before I implement these features (I am also considering releasing a new, more versatile plugin under a different name). Thanks for understanding.
That’s weird. I would have to take a look at the content of the file, could you upload it somewhere or post it on http://pastebin.com, please?
