cacti mbstring.overload has to be set to 0 when on same machine as egroupware

[el es]

Hi
this affects Ubuntu 8.04 LTS (all up to date):

http://ubuntuforums.org/showthread.php?t=1012019

In short : when egroupware and cacti are installed so they are served by the same apache, you never know, which apache instance is actually serving it; and since cacti cannot use '''php_value mbstring.func_overload''' it has to be set to 0 everywhere it is set otherwise, like in /etc/apache2/conf.d/egroupware change line 29.

So the /etc/apache2/conf.d/cacti.conf now reads:

> > Alias /cacti /usr/share/cacti/site
> >
> > <DirectoryMatch /usr/share/cacti/site>
> > Options +FollowSymLinks
> > AllowOverride None
> > order allow,deny
> > allow from all
> > # <IfModule mod_php4.c> # modify here
> > AddType application/x-httpd-php .php
> >
> > php_flag magic_quotes_gpc Off
> > php_flag short_open_tag On
> > php_flag register_globals Off
> > php_flag register_argc_argv On
> > php_flag track_vars On
> > # this setting is necessary for some locales
> > php_value mbstring.func_overload 0 # here is the clue
> > php_value include_path .
> >
> > DirectoryIndex index.php
> > # </IfModule> # and here
> > </DirectoryMatch>

I don't know if the ifmodule modification is meaningful at all, but I haven't tested it without, and with the file reading as above, it works flawless.

Hello,

I'm using Ubuntu 8.10, cacti 0.8.7b-2.1ubuntu2, egroupware 1.4.004-2.dfsg-1 and php5 5.2.6-2ubuntu4.1.

Using cacti alone on a tab (IE or Firefox), it works fine.

But when I use egroupware on another tab than cacti (IE or Firefox) and I go back to cacti, cacti shows:
"Warning: mb_ereg_replace() [function.mb-ereg-replace]: mbregex compile err: premature end of char-class in /usr/share/cacti/site/include/global.php on line 86

http://.../egroupware/admin/phpinfo.php shows:
"

...
mbstring.func_overload 7 0
"

So, the entry on cacti.conf doesn't works.

@cviniciusm, this is probably belated - but please read my solution throughly :

- in /etc/apache2/conf.d/cacti.conf, comment out the <IfModule mod_php4.c> line,
- and the corresponding </IfModule>,

- modify line that has mbstring.func_overload,
- to contain mbstring.func_overload 0

(i.e. not 7 0)
(for clarification, read php docs on mbstring.func_overload)

This works for me (still on 8.04 LTS with that server).
