Dolphin 7.0.9 - Got http 500 error when importing translation file

I just installed Dolphin 7.0.9 and I tried to import my custom language file but I got http 500 error (saying that  a error occurred while retrieving "http://mydomain/administration/lang_file.php"). I basically exported the original lang_en.php and replaced some Chinese words in the file, didn't make any invalid changes, and don't know why this error would happen. BTW, I have tried to rename the translated file to lang_zh.php, lang-zh.php and lang-zh-tw.php, as well as set "Name" and "Flag" to "zh" and "tw", just couldn't get the correct result.

Any idea or suggestion would be highly appreciated, thanks!!

theres not an error in the lang file otherwise you will get a php error. Its a server error check to see that a .htaccess file is in the langs directory is present.

The .htaccess file is there in the langs directory. Should I do anything with it?

lol its admin directory. Check the administration directory for .htaccess and post the file content here. You getting this error only with that particular file so maybe its a file permission problem

<IfModule mod_rewrite.c>

RewriteEngine off

</IfModule>

======================

The content of .htaccess under administration folder has only 3 lines as the above, and it's permission is 644.

oh, i am out of clue and can't tell much without looking into it and i am kinda busy now

You can wait for some more replies and if its really urgent just reinstall your dolphin.

I just reinstalled the website but the same error, have no idea why...

Thanks for your kindly help anyway.

take a look at folder permission list at 

http://your-site/administration/host_tools.php (permission tab)

maybe it show something

I just tried to make a second lang_zh.php with simply some words replaced and then do the import, and it works! So I'm pretty sure it was my first lang_zh.php's problem, I will now be more careful of the second one. Again, thanks a lot for your help.

 quite strange because php files don't cause server errors. Atleast i know that it doesn't. Maybe i am wrong anybody can correct me if i am wrong.

I did read somewhere on this forum, that unless you unload all the installed modules first, you will not be able to install a new language...

But if you uninstall all the installed modules, wouldn't you loose all the data you put into them?

It must to be a better way to put a new language into Dolphin, right now i can download the default english php language file but i can't upload anything, it gives me an error message all the times...
