[TYPO3] realurl issue

[4mails at gmx.de]

Hi folks,

We have been working with the realurl extension some time ago.

Many sites were correctly implemented by using this nice extension, however
a couple of months ago we are having serious issues trying to configure this
extension on a typo3 installation. 

First of all, the site mentioned has all requirements to work perfectly:

- We updated the source version from 3.8 to 4.0, and lately to 4.1.5 (we’re
getting the same error with 4.0 or 4.1.5)
- After that, we updated all the tables from the database, ant it’s
appearing to work right
- We reinstall the extensions required like, realurl, and tt_news, without
running into problems
- We add the extra configuration at the vhost.conf files, all the lines
recommended at the realurl’s tutorial were included (actually we used the
code lines from other sites configured and working correctly on the same
server).

Now we’re getting an error like this (enabling SQLDebug in Typo3):

Warning: mb_ereg_replace() [function.mb-ereg-replace]: mbregex compile err:
premature end of char-class in
/var/www/vhosts//<domain.com>/httpdocs/typo3conf/ext/realurl/class.tx_realur
l_advanced.php on line 744

This error refer to the following line:

744:   $processedTitle = ereg_replace('[^a-zA-Z0-9\\' . $space . ']', '',
$processedTitle); // strip the rest
       $processedTitle = ereg_replace('\\' . $space . '+', $space,
$processedTitle); // Convert multiple 'spaces' to a single one
       $processedTitle = trim($processedTitle, $space);

       if ($this->conf['encodeTitle_userProc']) {
             $params = array('pObj' => &$this, 'title' => $title,
'processedTitle' => $processedTitle);
             $processedTitle =
t3lib_div::callUserFunction($this->conf['encodeTitle_userProc'], $params,
$this);
       }
       // Return encoded URL:
       return rawurlencode($processedTitle);

This error appears
- when I’m logged in as a backend user and try to browse the website at the
frontend (the error appears all the time here)
- when I’m logged out as a backend user, browsing some pages at the frontend
(cannot establish a pattern yet)
- All module pages are working fine

At the bottom of this message, you can find the .htaccess as well as the
vhost.conf lines. We have tried activating one of the files and also both,
without success. 

Thanks in advance for your help.

.htaccess
---BEGIN---
#####
# 
# Example .htaccess file
# 
# This file contains a collection of almost everything you will need
# for optimising TYPO3:
# 
# - mod_rewrite (used for SimulateStaticDocuments, RealUrl, etc.)
# - PHP optimisation
# 
# If you want to use it, you'll need to rename this file to '.htaccess'.
# (To make this work you will need to adjust the 'AllowOverride'
# directive in your Apache configuration file.)
# 
# IMPORTANT: You may need to change this file depending on your TYPO3
# installation!
# 
# You should change every occurance of TYPO3root/ to the location where you
# have your website in. For example:
# If you have your website located at http://mysite.com/
# then your TYPO3root/ is just empty (remove 'TYPO3root/')
# If you have your website located at http://mysite.com/some/path/
# then your TYPO3root/ is some/path/ (search and replace)
# 
# If you have problems with this file, try using the minimal
# mod_rewrite.htaccess which is located in the typo3_src/misc/
# directory of this installation.
# 
# You can also use this configuration in your httpd.conf, but you'll have
# to modify some lines, see the comments (search for 'httpd.conf')
# 
# Using rewriting in your httpd.conf is much faster, btw.
# 
# Questions about this file go to the matching Install mailing list,
# see http://typo3.org/documentation/mailing-lists/

### Begin: Rewrite stuff ###

# Enable URL rewriting

RewriteEngine On

# To assist in debugging rewriting, you could use these lines
# DON'T enable it for production!
# This will only work in httpd.conf, not in .htaccess files
#RewriteLog /var/log/apache/rewrite.log
#RewriteLogLevel 9

# If you use the RealUrl extension, then you'll have to enable the next
line.
# You will have to change this path if your TYPO3 installation is located
# in a subdirectory of the website root.
# 
# If you place this in httpd.conf, you cannot use this directive in any
case!
RewriteBase /

# Stop rewrite processing if we are in the typo3/ directory
# For httpd.conf, use this line instead of the next one:
# RewriteRule
^/TYPO3root/(typo3|typo3temp|typo3conf|t3lib|tslib|fileadmin|uploads|showpic
\.php)/ - [L]
RewriteRule
^(typo3|typo3temp|typo3conf|t3lib|tslib|fileadmin|uploads|showpic\.php)/ -
[L]

# Redirect http://mysite/typo3 to http://mysite/typo3/index_re.php
# and stop the rewrite processing
# For httpd.conf, use this line instead of the next one:
# RewriteRule ^/TYPO3root/typo3$ /TYPO3root/typo3/index.php [L]

RewriteRule ^typo3$ typo3/index_re.php [L]
RewriteRule ^/.+\.(.+)\.[0-9]\.html     /index.php?id=$1 [R=301,L,QSA,NE]

# If the file/symlink/directory does not exist => Redirect to index.php
# Important note: If you copy/paste this into httpd.conf instead
# of .htaccess you will need to add '%{DOCUMENT_ROOT}' left to each
# '%{REQUEST_FILENAME}' part.

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l

# Main URL rewriting.

# If you use Windows and SimulateStaticDocuments do not work, try adding a
# slash (/) right before 'index.php' below.

# The example shows how to rewrite only *.html and *.pdf files to index.php
# This may be helpful when using an extension that can generate PDF files
# on the fly.
# Example: RewriteRule .*\.(html|pdf)$ index.php [L]

# For httpd.conf, use this line instead of the next one that has no '#':
# RewriteRule .* /TYPO3root/index.php [L]

# For use with the RealUrl extension, you might need to remove the
# RewriteBase directive somewhere above and use this line instead of the
# next one:
# RewriteRule .* /index.php [L]

RewriteRule .* index.php [L]

### End: Rewrite stuff ###

### Begin: PHP optimisation ###

# All features below are left to the default if you don't change this.
# Simply remove the comment marks if you want to use some/all of these
# settings

# The PHP developers recommend disabling this feature. Do that.
# It's deprecated and is likely to be unsupported in future versions of PHP.
#php_flag allow_call_time_pass_reference off

# TYPO3 works fine with register_globals turned off.
# This is highly recommended!
#php_flag register_globals off

# PHP may not declare the argv & argc variables (that would contain the GET
# information).
# TYPO3 doesn't need this, so just turn it off.
#php_flag register_argc_argv off

# Magic quotes for runtime-generated data (data from SQL, exec(), etc.)
#php_flag magic_quotes_gpc off

# Order in which PHP registers GET, POST, Cookie and Built-in variables
#php_value variables_order GPCS

### End: PHP optimisation ###

### Begin: Miscellaneous ###

# Make sure that directory listings are disabled
#Options -Indexes
