Dear moderation team,
I was working with my webpage http://www.infochina.pro/opcional adding a widget for rss in functions.php.
I am pretty sure I didn't delete codes, I just added the ones for the widget. After saving saving it, it appeared the message HTTP 500 Internal Server Error. So now I can not access to the webpage in any way.
How can I acces again to the page to modify the webpage? I saved the originall codes for functions.php. Can you please help me?
Thanks in advance.
