Fatal Error on Accessing Wiki Areas

Fatal Error in special_class_wiki.php when Accessing Wiki Areas

I'm getting this error now I've got my htaccess setup correctly:

Code:

Fatal error: Call to undefined function mb_strtolower() in /home/xuni/public_html/vault/special_class_wiki.php on line 711

It happens when I try to access a direct wiki area, such as the home page, or indeed, any wiki entry.

My htaccess for reference (if it's this at all) is:

Code:

RewriteEngine On RewriteBase / RewriteRule ^showwiki.php$ showwiki.php [L,QSA] RewriteRule ^showwiki.php?title=(.*)$ showwiki/$1 [L,R=301] RewriteRule ^showwiki/Wiki:(.*)$ showwiki/$1 [L,R=301] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^showwiki/(.*)?$ showwiki_proxy.php [L,QSA]

PS, I suspect (though not certain) that the above htaccess code can't be behind the full ModRewrite SEO built into vBulletin (using the code found for it at vbulletin.com), so I had to place it first in the queue to get it to work properly.

You can't use VaultWiki's UTF-8 support unless PHP is compiled with Multi-Byte Functions. Just disable the setting to eliminate the error.

EDIT: "Fixed" for the next build. An error message will prevent enabling UTF-8 support when the server doesn't have multi-byte functions.

Any pointer on enabling it? I run my own VPS, so got some leeway, provided it doesn't trash the setup...

I'm aiming to have Russian sections to the site, so I'm guessing UTF-8 is going to be needed?

Just looking at doing this pegasus, I assume it's a matter of running this via command line? I've never done anything with compiling PHP before at this level, so any words of warning would be appreciated...

Yes, this is something that needs to be done at the command line. I haven't done this with PHP before myself; I have only worked with the command line personally to set up Xcache for this site. I suspect that messing up with PHP will take your site down, so make sure you find yourself a straighforward tutorial on compiling PHP.

Contacting my hosts, found out it's possible through WebHostManager. Once I've done it successfully, I'll let you know how it went, and try and put up a tutorial on it.

Seems this can be done through EasyApache in the WHM setup (may require root access, or permissions granted from the root owner), and would be VPS/Semi-Dedicated/Dedicated.

Simply load up the wizard on the EasyApache (Apache Update) in the Web Host Manager (WHM) for your server.

Much of the wizard is a matter of replicating existing settings, but when you get to 6. Exhaustive Options List, then add the mbstring to be installed (tick box), finish the rest of your settings, then save it. Backup everything. The Build the profile you've created, wait for it to finish, and hopefully you've got a working compile.

Doing it through cPanel and WHM at least allows you to get there help with support. I'd suggest you make a note of what versions of everything you were using before as well.

When I get a few minutes I'll throw this into a 'tutorial'.

(I was linked to this page for details on how it works: http://docs.cpanel.net/twiki/bin/vie...pache3/WebHome)
