In Admin->News->Modify Topic, it would decode the topic title if we try to modify it. We have to retype all again for all language title. But I found XOOPS is Good and well prepared. Lets correct this file.
Open /modules/news/admin/index.php
goto line 241 in function modTopic()
modify Quote:
<input type='text' name='topic_title' size='20' maxlength='40' value='".xt->topictitle().
tobe Quote:
<input type='text' name='topic_title' size='50' maxlength='50' value='".xt->topictitle('E').
This function used default format 'S' 4show (but we hacked). The function has been well prepared to accept parameter 'E' 4Edit format which we should use in this file.
Hope XOOPS developer update this file.
PS. I changed maxlength of title to 50 as database defined, and thinking why XOOPS defined 40 in this file.
