Yesterday i got a blank home page and thanks to the replies i worked it out. Then I got another non-english character problem. To figure this out i deleted the database and almost all files under webroot//xoops (some files refuse to delete). Then i uploaded the latest XOOPS and created a different database before the new installation.

At this time the non-english character problem was gone. Unfortunately a new problem comes to me (i got a new game called problem maker). i can ONLY see 'Log in' and 'Navigator'. There are nothing under log in, no name input field, no pwd input field, no submit button. Nothing under Navagator, nothing. So the total page is a header, a footer and two words 'Log in' and 'Navagator'.

What's worse, admin.php is totally blank. Surprisingly i can register a new account but cannot make accounts verified.

Worst part is that i tried：

2. try the query "UPDATE xoops_config SET conf_value=1 WHERE conf_name = 'debug_mode'".

and

3. then edit the file "include/common.php". Near line 83, change "error_reporting(0);" to "error_reporting(E_ALL);".

and

5. you can create a file called ".htaccess" to override the settings locally. This file should contain the line: "php_flag display_errors on".

but all of them were not working.

I tried to chmod all files and directories but mainfile.php to 777 too.
