[SOLVED]I have a problem with field name translations page does not open

[vallverd]

Hello
By accessing in admin-tools-field-name translations translations does not open the page and not seeing any error.

At the same time we APARE this error when printing invoices and bills, I think it may have something to do to put a new module and that affects the translations.

DESPUES INCLUDE /usr/home/vallromanesverd/www/tools/fpdf/fpdf.php
FPDF error: Some data has already been output, can't send PDF file
