I knew I made a syntax error or something which Wordpress showed error after I added code to functions.php :
Parse error: syntax error, unexpected 'Lucida' (T_STRING), expecting ',' or ';' in /home1/[name]/public_html/wp-content/themes/[name]/functions.php on line 49
The problem now is that, how am I supposed to rectify the problem when I tried clicking on any part of my website now, it will just show that error message without allowing me to even edit back the code?
I hit the 'back' button, and managed to go back to the theme editor, and removed all changes, to restore to its default and click 'update file'. It still showed me the same error.
I can't even enter my admin page of the Wordpress.
Can anyone help on this? Nothing I can do now?
I FIGURED OUT THE SOLUTION
I'm tired of waiting. I've fixed it on my own. Looking somewhere at Wordpress.org support forum and there were people suggested to ftp to the website, and edit back the functions.php file.
So the steps:
If you have control panel on your web hosting, you can either use File Manager on your control panel or ftp to your website using ftp client such as FileZilla.
Remove whatever faulty from the functions.php, and if you have to, restore to its default.
Click 'Save' and you are done. My problem fixed.
