ListView error (Tasks)

Hi everyone!

Trying to access Tasks module, and this is what I have in a syslog?

Sep 17 19:26:11 crm apache2: PHP Notice: Undefined index: ProjectTask_project in /var/www/html/st4/data/SugarBean.php on line 3125
Sep 17 19:26:11 crm apache2: PHP Notice: Undefined index: in /var/www/html/st4/data/SugarBean.php on line 3125
Sep 17 19:26:11 crm apache2: PHP Warning: require_once(/var/www/html/st4): failed to open stream: No such file or directory in /var/www/html/st4/data/SugarBean.php on line 3125
Sep 17 19:26:11 crm apache2: PHP Fatal error: require_once(): Failed opening required ‘’ (include_path=’/var/www/html/st4:/var/www/html/st4/include/HTMLPurifier/standalone:/var/www/html/st4/include/…:.:/usr/share/php:/usr/share/pear’) in /var/www/html/st4/data/SugarBean.php on line 3125

Actually, that line number is different beecause I’ve added some var_dumps hoping I’ll se whatrs going on :(, and it says:

require_once($beanFiles[$beanList[$joinModule]]);

Upgraded to 7.7.4, still getting this.

Any ideas?
