I had a module with no translation so I have exported .po file and make my own translations. I have created i18n folder with the generic .pot and my .po translation (each one in UTF-8). I have tried restarting the server with -update-all, updating the module, synchronizing translations... and nothing has worked.

If I create a new db there is no problem, the translation works but I would like to charge it in the other db.

Any solution?

Thank you in advance.
