It’s bad news.I just found that HTMLarea not worked in some language,ie danish,swedish.When i turn on HTMLarea editor from the zen cart backend for one of my website,then i found the HTMLarea not show in the product edit page.
With the help of Web developer(firefox addon), i found the HTMLarea editor need to load htmlarea/lang/sv.js when the site default language is swedish.but the sv.js is not existed at all.that’s why the editor not work.
form the js file path htmlarea/lang/sv.js,i guess the js file located in the subfolder lang are used to store translation for the HTMLarea.so i excute the following command:
cp en.js sv.js
after refresh the zen cart product edit page,the editor’s toolbar show out.This solution worked for all the other language that’s not supported by HTMLarea by default.The files under lang subfolder are usded to store tool tips for the corresponding language.
