Blank screen or empty response at login screen

[acli]

Pressing the “Log-in!” [sic] button at step 7 produces a blank screen at URL login.php?submit=%BB+Log-in%21

If we manually change the URL to just login.php we get an empty response. The headers are still intact and is 200 OK, but there is no content.

Tracing include/vitals.inc.php prompted me to test for the validity of the generated config.inc.php:

bash-3.2$ php -l include/config.inc.php

Parse error: parse error in include/config.inc.php on line 20
Errors parsing include/config.inc.php
bash-3.2$

Line 20 is the DB_PASSWORD which has a quote (U+0027)...

write_config_file() is in include/install/config_template.php

write_config_file() uses a simplistic str_replace() on a template string. We are stuck.

I was suggested that addslashes and stripslashes should be $addslashes and $stripslashes. But doing that caused “Fatal error: Function name must be a string in /Users/ambrose/Sites/projects/ATutor/include/install/config_template.php on line 37” error.”

Using call_user_func with $addslashes apparently works, but it generates

Warning: call_user_func() expects parameter 1 to be a valid callback, no array or string given in /Users/ambrose/Sites/projects/ATutor/include/install/config_template.php on line 37

The real problem should be include/vitals.inc.php not having been included. It looks like we’re supposed to include it upstream as opposed to include_once where it’s needed…
