Translate file save error

-- HikaShop version -- : 2.3.5
-- Joomla version -- : 1.5.26
-- Error-message(debug-mod must be tuned on) -- : Could not save the file invalid filename

I have a problem. The system/configuration reports that there is a translation in my language. Simply, did not save the file. Could not save the file invalid filename Please help.

Hi,

Please give us more details, through for example some screenshots.
Where are you editing the language file, form HikaShop > Configuration > Languages ?

The full error message could help us to find the issue

Hi,
I've the same problem, when I go to HikaShop > Configuration > Languages and press Save button, also if i've not made some changes, appear this error "Could not save the file invalid filename", and the systems don't save the changes.
In folder languages there is the last version of language file (it-IT.com_hikashop.ini), the problem seem linked to name of the file where are saved the languages modifications, (the second text area, Overwrite:), if a second language file exist, where it should be ?

What can cause the issue ?

Many thanks

Luca
