The Joomla! community just completed migrating from SMF over to phpBB3. Brad Baker posted some of the details on the reason for Joomla.org’s use of phpBB3. The main reason to move over to phpBB stemmed from Joomla.org’s discomfort from bridging GPL applications with non-GPL applications. Baker says :
Why did we move to phpBB3?
Good question, and there is a simple answer. Whilst SMF was great for us, it is not licensed under GPL, and as a result many of our users who like to follow the choices we make were going to run in to integration issues in the future. As well as that, the team at phpBB have been great, with many of them offering to help, especially with the conversion.
In any case, we’re not going back, and the future is phpBB3!
500 Internal Server Error on Localhost for Web.Developer Server Suite was pissing me off for a long time. The Apache error logs shows “RewriteEngine not allowed here”. Deleting .htaccess would fix the problem, but here is the fix. It’s a problem with mod_rewrite module and Apache’s AllowOverride configuration. Here’s how to fix it :
Firstly, make sure LoadModule rewrite_module modules/mod_rewrite.so is enabled in httpd.conf (Remove # before the line to enable)
Then, edit httpd.conf .. Find out the foll lines and mod -
<Directory “/www/vhosts/localhost”> #replace this with your dir name
Options Indexes FollowSymLinks
Order allow,deny
Allow from all
AllowOverride All #Added
</Directory>
<Directory />
Options FollowSymLinks
# AllowOverride Limit #Old Value
AllowOverride All #Added
Order deny,allow
Deny from all
Satisfy all
</Directory>
Was working on Seryet all day to fix errors like
Notice: Undefined variable: fullmd5cachefile in \localhost\components\com_seyret\plugins\videoserver\metacafe.php on line 226
Notice: Undefined variable: vdlink in \localhost\components\com_seyret\plugins\videoserver\metacafe.php on line 226
Notice: Undefined variable: fullmd5cachefile in components/com_seyret/plugins/videoserver/google.php on line 399
Notice: Undefined variable: showfrombackupbutton in components/com_seyret/seyret.php on line 2115
Finally figured out a way to get rid of these ..
Open up seyret.php in components > com_seyret [ and admin.seyret.php in administrator > components > com_seyret, if errors come up in the Admin panel too ]
Add error_reporting(E_ALL ^ E_NOTICE); to seyret.php and admin.seyret.php and voila !
