It looks like below:

So I open the Web Developer Tools of the browser Firefox. Check the Network.

Refresh the page.

There is one 500 error on the site.

/wp-admin/locad-styles.php?**********

It is a script to combine the styles into one file. Then it is broken.

The solution I found on Google is to add a configuration line into the wp-config.php file.

Open the wp-config.php file.

Add the following before the require_once.

define('CONCATENATE_SCRIPTS', false); 

Then, refresh the Admin page. It looks OK.

All the CSS files are loaded individually.

The real reason, I believe, is because the Plugin or Theme has a small compatible issue with the WordPress program.

FastCGI sent in stderr: “PHP message: PHP Parse error: syntax error, unexpected end of file in /your_path/yourscript.php on line 308” while reading response header

This is the error when I check the php log file. Because I met the blank page with 500 internal error, which is loaded OK on the other server.

The real reason is I use (<? ?> ) and (<?php ?>) in mix. So I faced with this parse error when running the script on different systems:

Parse error: syntax error, unexpected $end in X on line Y

where X is the file path and Y the line number, usually the last line of the file. But the shotform may not there.

To avoid this error, refrain yourself from using the short form and stick to ( <?php ?>), despite the extra 3 characters. This will make your code universally accessible and it is essential if your developing for beyond your own personal use. If you insist in using the short form (<? ?> ), and you get this error, you can enable the short form option in the php.ini file.

short_open_tag=On

Keep in mind though, that the short form is supposed to be deprecated in PHP 6. If this goes through you will have to go back and change all your source files.

In the furture, I wil keep using long form of it only.

And also with Access database.  The page is try to add new record into the Access database file. But the browser return 500 internal error. The detail error code in log file is 800a0cb3 with the description: Recordset does not support updating. This may be a limitation of the provider or of the selected locktype.

I did a lot of research and found it is a right issue.

Now it is the solution:

Add “Authenticated Users” to the Access mdb file, with full access right.

Then, no more error, the data can be added as design.
