AND HERE IS THE ERROR:
An Error Was Encountered

Unable to load the requested language file: language/validation_lang.php

[eluser]manilodisan[/eluser]
system/language/validation_lang.php. See if that file is present there....

[eluser]LuckyFella73[/eluser]
Looks like you have defined a language in application/config.php
that is not available in system/language/(your language)

Did you allready check this?

[eluser]xwero[/eluser]
As i look at your labels it's not English So is suspect you have set the default language to your own in the config.php file. If you have not copied the validation_lang.php file to the application/language/[idiom] directory the language library will not find the file.
