problem with "updating apache"

Yesterday when i login whm, i saw a red warning at the top of whm, it is said:
You are running an insecure Apache setup. You should run
/scripts/easyapache or if you are running cPanel 7.1.9 or later (click
here) to upgrade to a newer version as soon as possible to avoid your
system being compromised.

Then my friend help me to recompiled apache. After this, the red warning is gone. But now we got this message in whm:
Important Notice: Incompatible versions of Mysql 4.0.x and NPTL based systems.
If you are running a newer linux system which is NPTL based (CentOS 4, Fedora 3+, RHE 4, etc) and are having problems with MySQL 4.0.x (versions later then 4.0.23*), we recommend upgrading to MySQL 4.1.x as we have determined that there are compatibility issues on these platforms. You can easily upgrade to 4.1.x by changing the Mysql Version in Tweak Settings
If you are worried about compatibility with MySQL 4.0, be sure to check the box labeled: Use old style (4.0) passwords with mySQL 4.1. in Tweak Settings.
If you are unsure if your system is NPTL based, run getconf GNU_LIBPTHREAD_VERSION at the command line and see if it displays NPTL.
* 4.0.23 does not have any known issues, but is subject to security vulnerabilities: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-1516, http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-1517
Severity:

And now we find some problems. i.e.
1. when we click the login button of typo3(one script installed on our site), the page is gone. It seems we can not run certain scripts.
2. we can not visit www.mydomain.com/oscommerce, but it is funny when i set the username/password to protect it using "password protect directories" in cpanel, it can work. After i remove the username/password, it still can work.

What is the problem? What shall i do? Many thanks in advance.

 

The below message is from my friend. He helped me with this issue yesterday.

Since we have a more recent version of CPanel. I have run the "click here" link instead of the SSH option. It takes me to a build window.
This build window is a bit tricky (I've played around with it a bit last year) so I've run the recompile myself.

If you need to recompile apache again you should always check to use the "load previous configuration" otherwise it sets itself to the defaults which don't work as well.

The build is still happening now so you may see some downtime. I'll email you when its done.

Now i have this problem:I try to login my webmail http://www.maxsource.net. But i got the below error:
Fatal error: Call to undefined function: _() in /home/max/public_html/mail/config/registry.php on line 90

Sorry for this. And thanks for your reminder. I will not do that.
