1. The plugin was never deactivated.
2. Only auto translation was used. Way below quota used.
3. The site was developed in English only; Thai was never added to the text. It was partially translated by the plugin.
4. Words like Series on a page are sometimes not fully translated eg 70% of “series”is translated.
=> I have rebuilt the home page by replacing all Thai text with the original English text.
=> I will try manual translation of words like Series. I will use another plugin if it still doesn’t translate fully. Thanks!
