[Gelöst] Additional performance-related issue

Hi,
We are trying to improve the speed of our website, and found several WPML recommendations that say to enable:
“Store strings in .mo files” / “String translation via .mo files”
“Use cache for string translation”
However, these settings do not appear anywhere in our WPML interface — neither under String Translation nor in any other WPML settings section. Could you please confirm whether these options should be available in our current WPML versions, and if so, how to enable them?
Thank you very much for your help.
If you need any additional details, we will gladly provide them.
Best regards,
Barbora
