I wrote this original post but I'm replying from this email that I have
to use since my system isn't processing email. Interesting that this one
got through, as I never received it to the original address. So this
email may be somewhat tied to my other post about upgrading clamav and
email no longer working. Amazingly, I might have been right about that
since this email went through after I upgraded Webmin, and after I
upgraded qmailadmin. FYI I mentioned in my other thread that I fixed the
qmailadmin 500 internal server error by creating a symlink to the
libmysqlclient.so.15 in /usr/lib. I created symlinks to the others while
I was there, even though this alone fixed it:
cd /usr/lib
ln -s mysql/libmysqlclient.so.15.0.0 libmysqlclient.so.15
I still don't know why I needed to do this, since /etc/ld.so.conf
includes this line:
include ld.so.conf.d/*.conf
and ld.so.conf.d/*.conf points to /etc/ld.so.conf.d/mysql-i386.conf,
which includes this line:
/usr/lib/mysql
which is the directory that includes libmysqlclient.so.15 (symlink to
libmysqlclient.so.15.0.0). Smelled like a permision issue to me
yesterday, and still does.
getenforce command indicates disabled.
I've also just noticed squirrelmail is down (blank white screen). Log shows
PHP Warning: require_once(../config/config.php) [<a
href='function.require-once'>function.require-once</a>]: failed to open
stream: Permission denied in
/usr/share/squirrelmail/functions/global.php on line 92
PHP Fatal error: require_once() [<a
href='function.require'>function.require</a>]: Failed opening required
'../config/config.php' (include_path='.:/usr/share/pear') in
/usr/share/squirrelmail/functions/global.php on line 92
So squirrelmail and qmailadmin not working: fairly certain a result of
the Webmin upgrade, v1.410 to v1.490, as nothing else interesting going
on prior to that.

I know next to nothing about webmin, so I'm afraid I'm can't be much
help. I would however be inclined to reinstalling mysql with --force
option instead of adding a symlink manually that the package should
provide. If the symlink somehow got hosed, who knows what else in the
package is amiss?
