I’m not sure if you’re aware, but this is a rating / review thread.
If you’d like to ask a question, you can post your question here: https://www.ads-software.com/support/plugin/wpsso/
The information you provided is a but unclear though, so when you post your question, maybe add how you’re trying to activate it, and how you’re trying to delete it. The WordPress plugins system is usually pretty robust – installing, activating, deleting plugins is pretty easy, so it sounds like there may be a larger issue here. ??
Once you activate the plugin, I’m sure you’ll enjoy it. I’m not sure rating it before actually trying it is the correct thing to do… Moderators, what do you think?
Thanks,
