Help installing a mediawiki

[callumacrae]

I'm installing a media wiki, but when ever I try to access cofig, it says:

Warning: shell_exec() has been disabled for security reasons in /home/alexmac/public_html/tutorials/mediawiki-1.12.0/config/index.php on line 1822

And that is the last thing I see in the source code as well.

My PHP version is intermediate, but I don't know much PHP, and so I don't know what to do.

Please can I have some help?

Thanks in advance.

It is what it says, that function has been disabled by x10 staff for security reasons.

try

<?php
phpinfo();
?>

And you'll see this somewhere (for the intermidate version):
suhosin.executor.func.blacklist
passthru, leak, listen, diskfreespace, link, dl, exec, system, source, fpaththru, virtual, posix_ctermid, posix_getcwd, posix_getegid, posix_getgrnam, posix_getlogin, posix_getpgid, posix_getpgrp, posix_getpid, posix_getppid, posix_getpwnam, posix_getrlimit, posix_getsid, posix_kill, posix_mkfifo, posix_setegid, posix_seteuid, posix_setgid, posix_setpgid, posix_setsid, posix_setuid, posix_ttyname, proc_open, proc_close, proc_get_status, proc_nice, proc_terminate, ini_alter, mb_send_mail, proc_open, pfsockopen, openlog, syslog, apache_child_terminate, apache_get_modules, apache_get_version, apache_getenv, apache_note, apache_setenv, virtual, shell_exec

So you'll never get this function to work.

Possible solutions:
- Maybe it is allowed in the advanced php version? (Hint to some kind mod ^^)
- Try to find a way to do the same with a different function.
This is what php.net has to say about shell_exec().

I hope I was able to help you,

Well, I know that kllctcat has a mediawiki on his website, but he is a moderator, so maybe they have different settings.
Isn't it meant to be really hard to get advanced PHP though?

The strange thing is, is that on line 1822 I can't see anything saying shell_exec()
I can't find it anywhere in the file.

I have MediaWiki installed and running so it is posible, but I have the Advanced PHP version.
You could try to request an upgrade, and see if it will be accepted. Or you could try a different Wiki system (there are many out there including pmwiki, DokuWiki and WikkaWiki).

Alex, when I was looking for info about your problem, I found out shell_exec() is connected to the operator ` (as in ò, ì, à).
The code

$string = shell_exec("command"); 

is the same as saying

$string = `command`; 

And as I said before, maybe it does work with the advanced version. (once more, hinting to some kind mod)
and it's always worth trying to get it ;-)

The best thing to do would be to post a thread in free hosting support about requesting an upgrade to advanced PHP for installing media wiki.

Corey or Brandon or Bryon would then look into it and let you know a reply.

Thanks for all the help, I have asked for an upgrade to advanced PHP. I just hope they upgrade!

[galaxyAbstractor]

it's fun because I have mediawiki installed but I never got that error. But I may have a old version... Try to comment that line. In some cases it works.

have you tried asking for a less strict php version on your hosting cp?

that is what we were talking about the whole time...
the advanced version is the less strict version. he's now requesting an upgrade.
