I am trying to install fresh copy of SuiteCRM 7.5. and was unable to do so because of following JS error:
install.php:19 Uncaught TypeError: Cannot read property ‘focus’ of nullonload @ install.php:19
The problem is that there’s no element with id = button_next2 in current DOM and focus method is called
Actually what happened is that I wasn’t warned about requred PHP version (5.4) and then AOR_Reports throw fatal error because of new array bracket syntax.
Then DOM was delivered to browser and didn’t contained the button which jQuery tried to focus.
You should either check for required PHP version or even change back those 5 or so occurrences of new PHP 5.4. array bracket syntax in modules/AOR_Reports/AOR_Reports.php
