typo3: fix dark pictures

posted on 2016-03-10 12:39:14

If after an update, a migration or for whatever reason your typo3 installation shows pictures being too dark, your installation very likely uses the wrong color space. Like RGB instead of sRGB.

To confirm this, grep for colorspace RGB in your typo3 installation files.

You very likely have to change like three occurences in t3lib/class.t3lib_stdgraphic.php:

-colorspace RGB

is to be replaced with

-colorspace sRGB

Log into the Backend afterwards, und click on the spark symbol on top to clear all caches. (After you have chosen your site in typo3's file tree.)

If you do not have a login, create a file called ENABLE_INSTALL_TOOL in typo3conf, and comment the original line out and add this line:

$TYPO3_CONF_VARS['BE']['installToolPassword'] = 'bacb98acf97e0b6112b1d1b650b84971';

in typo3conf/localconfiguration.php, so you can access the install tool at with the default password joh316. There you can add a new admin user.

After having cleared the caches and confirming everything still works as expected, remove the ENABLE_INSTALL_TOOL file and delete your newly created backend user, and fix the install tool password in localconfiguration.php back again.

To be exact there is no reason to use graphicsmagick or change any configuration variables besides the color spaces for image rendering and clearing the caches afterwards.

typo3: password reset

admin password for the backend through mysql

UPDATE be_users SET password=md5('your_new_password') WHERE username = 'admin';

reset install tool password

In [your_site]/typo3conf/LocalConfiguration.php do:

$TYPO3_CONF_VARS['BE']['installToolPassword'] = 'bacb98acf97e0b6112b1d1b650b84971';

This will give you the default password of joh316 again.

This stuff comes from the manual here.

typo3: access without password

To gain access to typo3 backend without having a working set of credentials, you might either try using the mysql client and directly add the user to the database, but this is kind of unwieldy.

Easier it is to use the typo3 install tool.

On a proper install this can be accessed via http://<>/typo3/install from your browser, where you will be prompted for the install password. Since it is extremely likely that you do not know it anymore, change it to one you know. Also the install tool is very likely deactivated. typo3 may tell you in the login mask, which file to create on the server so you can access the web interface afterwards. For me it was to create an empty file called ENABLE_INSTALL_TOOL in the typo3conf folder of the typo3 install.

To get a working password, you have to swap the md5 hash of the password in the <path-to-your-typo3-install>/typo3conf/localconf, or in typo3 versions prior to 6.0 in the localconf.php file. Have a look at the typo3 documentation what to do exactly, as this can change with new typo3 releases.

To get a working hash, simple enter the password you want in to the install tool webmask. The login will fail and the tool will tell you the hash of the password you wanted to use.

Once you are logged in, choose the 'Database Analyser' menu, in there you should be able to create a new 'admin' user.

With that one you can login into the backend.

Do not forget to cleanup after you (remove the ENABLE_INSTALL_TOOL file from the typo3conf folder).
