Did you get it as soon as you activated the plugin, or you’ve been using the plugin already, and got this after?_ 3. _Is the plugin still activated?

We have analyzed the errors, and I came up with a conclusion and asuggestion for you, which I am sure will do the trick.The problem is that your host/server is most probably missingthe iconv extension. This is a straightforward fix but **not** something we canperform within our plugin. It’s very rare for this PHP module not to be already running, but once activated, I am confident things will get back tonormal.Can you please contact your hosts/server admin as request that the iconvIs PHP extension enabled?Let me know how this goes or/ and if you require further assistance!Kind regards.
