edit view of a taxonomy is not being displayed

Dear,
i have installed this plugin in two different projects, the first one is working perfectly and once I click on any taxonomy term it opens directly , but in the second project this action is not working at all, once I click on any taxonomy term the ajax loads, and then stops without displaying any information related to this taxonomy term,

I have termstatus module installed, term_revision, term_authoring information, term_siblings_order, term_search, term_filters_by_view,

and I have a huge load of data in this Vocabulary, up to 4000 term, between parent and children

always stating the AJAX ERROR OCCURRED all though the data is Response code 200,

I guess it's related to replacing the TITLE, with name_field, for translating content as The website is multilingual,

I would much appreciated if any one can help me.
