Typo3 Problems with image gm convert and umlauts

If you have a problem when uploading images with umlauts in the file name you first stop may will be to check the config.local_all setting. The setting should match some value of the locale -a command of the server. Mose of the time it’s something like en_US.uft8 or de_DE.utf8.
But if you still getting errors like

/usr/local/bin/gm convert: Unable to open file ([image file name]) [No such file or directory].

You should also set systemLocale of the Typo3 configuration. The most simple way to do this is to use the Installation Tool/All Configuration:

$TYPO3_CONF_VARS['SYS']['systemLocale'] = 'de_DE.utf-8';

Plesk: mysql admin password

Since Version 10 it’s possible that the password of the mysql database of Plesk is, well they call it encrypted. This is basically fine, but may can run you in some trouble. For example if you like to install you own global phpMyAdmin installation and then try to log in as admin.

You’ll first try will be to use the same password as you will use when log in to Plesk. That will not work! Then you’ll may step over the ssh shell and type in

cat /etc/psa/.psa.shadow

This will give you something like

$AES-128-CBC$X...==

Yeah … that looks like the password is encrypted. As Plesk admin you know an other way to get the password

/usr/local/psa/bin/admin --show-password

This will output the password you already tried. Then you’ll dig around the internet and may find this cmd

mysql -uadmin -p`cat /etc/psa/.psa.shadow`

And … it’s working! You get access to mysql. Hmm … now you’re may a bit confuse. But thing about it. If you want to access your mysql database outside of Plesk you have to use the whole output of

cat /etc/psa/.psa.shadow

as password! Even if it look like it’s encrypted. This is your database password!

 
If you don’t like to have such a super long password and can live with a plain text password in the file /etc/psa/.psa.shadow you can change it back. But remember to repeat this every time you change the password via the Plesk panel 🙂

/usr/local/psa/bin/init_conf -u -passwd 'some_password' -plain-password

 
Alternative you can add an other user with full admin rights to your database.

Typo3 cli_dispatch.phpsh scheduler Exception ‘localconf.php is not found!’

After a system update or something else it may happen you get an Exception of your Typo3 Installation. It’s not always the main site but can also could be your “cron” scripts (cli_dispatch.phpsh)

Fatal error: Uncaught exception 'Exception' with message 'localconf.php is not found!' in ../t3lib/config_default.php:707
Stack trace:
#0 ../typo3/sysext/cms/tslib/index_ts.php(128): require()
#1 ../index.php(84): require('...')
#2 {main} thrown in ../t3lib/config_default.php on line 707


or

Fatal error: Uncaught exception 'Exception' with message 'localconf.php is not found!' in ../t3lib/config_default.php:707
Stack trace:
#0 .../typo3/init.php(206): require()
#1 .../typo3/index.php(63): require('...')
#2 {main} thrown in .../t3lib/config_default.php on line 707

Of course the line numbers could be different 😉
So …. what’s the problem? It so simple that you just forget how you solved it the last time. “Last time? I don’t remember that there was a last time!?”. But you did!
Just check the php.ini and ensure that safe_mode = Off is set. Furthermore check the open_basedir setting. Ensure that (when used at all) all needed directories are set.

How to speed up page rendering?

Today just a shorty: Enable gzip!

When using php set output_handler = ob_gzhandler. So every php request will be compressed.

Also you can use the defalte module of you apache2. In that case javascript, pure html and css will also be compressed.

  • activate the module a2enmod deflate
  • add some lines to you configureation (vhost or globle whatever you want) (global in this case)
    <Location />
    <IfModule mod_deflate.c>
    AddOutputFilterByType DEFLATE text/html text/plain text/xml text/php text/css text/js text/javascript text/javascript-x application/javascript application/x-javascript text/x-js
    </IfModule>
    </Location>
  • Don’t forget to restart the server! Do not just reload the configuration!

PS: To check the content-type on a linux command line of a web page try
lynx -head -dump http://www.google.com
