Hi!
Thanks for your help, im not sure if this is what you told me to do, but it is what i have done and it worked like a charm:
1 Download “pmpro.pot Updated translation 2 months ago”
2 Copy the few lines that i needed (price and renew lines) and then update those lines with my translation then include them into my pmpro-es_ES.po
3 Upload the new po file to the server and convert the po to an mo, (there is lots of tools out ther to do so) and upload it to the server as well.
The reason why i didnt changed one file for another is basically because i changed a lot of things in the translation files, not just those 2 words so i dont want it to be overridden by a new file.
Thanks so much for you perfect plugin and your kind support.
