Moodle needs the pathinfo from the web server to function. This switch is there to prove whether there is this incompatibility. That is what the warning says. (Never noticed this warning, maybe that problem never existed in those servers I worked.)

The long-term solution is a setting somewhere in your web server. Better ask your hosting provider how to activate it.

 

P.S. Yes, this is not a developer question, for the Installing and upgrading help forum rather.

So you see part of the page? Or, the whole page is white?

Either way Debugging Leon mentioned is the starting point. Note that if you get a white screen you have to read the web server logs.

 

Did you check the server requirement before upgrade by going to Server administration > Server > Environment? Operate the drop-down with Moodle versions.

 

Since you can't enter that page now, compare your notes agains http://www.syndrega.ch/blog/#php-and-dbms-compatibility-of-major-moodle-releases.

Site administration > Server > Environment is all green?

Academi is not a standard theme. Switch to Boost and compare.

Hint: If the Moodle front-end doesn't come up, you can add the following line to moodle/config.php:
$CFG->theme='boost';

It sounds complicated but I want to ask whether you are in fact giving the candidate infinite time but want to know how much time he consumed. If so, don't set any time restrictions but make clicking the submission button a must. Moodle records the start and the end times.
