Hi @serraniandrea
It is not possible to downgrade the data from ACF PRO to ACF4, however it is possible to use the export to PHP feature as both ACF PRO adn ACF4 use the same code format.
As for the original question, I’m not sure I understand what is going wrong.
What do you mean by set a qTranslate text field?
I have tested qTranslate with ACF PRO and the ACF fields appeared on both languages. Perhaps you can include steps to replicate the issue?
