Translate was disallowed for HTML input in a view- how to enable?
By default, Filtered HTML and Full HTML are not available for translation.  You can override this by enabling the i18n module and visiting:


/admin/config/regional/i18n/strings (on Drupal 7)
admin/settings/language/configure/strings (on Drupal 6)


Just check the boxes for the text formats which you wish to enable.

Depending on your situation, you may also need to enable the i18n Views module.
