I've noticed that  users have got issues with PrestaShop translations feature. I described how to fix max input vars issue in this article: PrestaShop max input vars - how to fix the issue. This is default method to fix this issue. In some cases - some of hosters have got different way to define own php.ini file. GoDaddy hosting also. To change max_input_vars limit on GoDaddady hosting you have to create php5.ini file with contents:

[PHP]
max_input_vars = 5000

Save file as php5.ini in root dir of your hosting account / prestashop installation directory. Should solve problems. Of course you have to define own value of this param. So instead of 5000 use value depending on your needs described in error message.
