Hi,

I recently upgraded from php4/apache1.3 to php5/apache2.2. Now some topics on the forum don't display any more. In the errorlog is this error:

8: Undefined offset: 0
File: /home/xxx/public_html/joomla/components/com_smf/smf.class.php
Line: 455

or

8: Undefined offset: 0
File: /home/xxx/public_html/joomla/components/com_smf/smf.class.php
Line: 449


This is line 441-462 from smf.class.php. It has something to do with $matches[0] returning a empty value I think. Something similar as in this topic: http://www.joomlahacks.com/component/option,com_smf/Itemid,94/topic,2503.0 [nofollow] Only there it is a notice, and on my site the forum disappears.

Code Select
            if (empty($headers) || empty($keywords) || empty($css)) {
                //if one is empty rebuild all
                $headers = '';
                $keywords = '';
                $css = '';
                $this->debug .= 'loading headers';
                $regex = '/<head>.*<\/head>/smi';
                preg_match($regex, $buffer, $matches);
                $headers = $matches[0];

                $regex = '/name="keywords" .*" \/>/i';
                preg_match($regex, $headers, $matches);
                $search = array ('/.*content="(.*)".*/i');
                $replace = array ('$1');
                $keywords = preg_replace($search, $replace, $matches[0]);

                $regex = '/<link rel="stylesheet" .*" \/>/';
                preg_match_all($regex, $headers, $matches);

                foreach ($matches[0] as $key => $val) {
                    $css .= $val."\n";
                }

I did some research, and I found only 1 other person with the same problem. It was caused by an corrupted table. All my tables are fine according to MySQL. I also noticed that these forumtopics are only not readable by moderators and higher, and some members. When I log out, or log in to a normal user account the topic displays just fine.

I'm running joomla 1.1.13, SMF 1.1.4, JSMF 2.0.2.1 with php 5.2.5 en apache 2.2.6.

As you may have noticed I'm using the bridge from joomlahacks.com [nofollow], but they are no longer giving support and the forum is dead, so I hope that someone over here can help me! I haven't got any replies on joomla.org [nofollow] so far: http://forum.joomla.org/index.php/topic,247433.0.html [nofollow]

Unfortunately, you'll find better support at joomlahacks.com for that integration than you will here.

You're welcome Michaelnl,  unfortunately that bridge had quite a few issues... It is disappointing that it is not supported better...
