I tried to translate the English terms that appear in the search options. The Post type radio options are Products and Pages. I can select these in Translatepress alright and the translation dialogue appears. However the default language of the site is Spanish. This means that all untranslated terms are considered in that language. The Spanish field says Products and the English field is blank.
This incompatibility is for me a reason to request a refund. Would it be granted? Is there an alternative?
