I played around the PHP version update for MOODLE 3.1 to run PHP 7.0 , I think it was running on PHP 5.6 earlier on and possibly I have not activated all the necessary PHP Extensions. Now I am having queer pages and the Site Administration link is not active as a link. I reverted to PHP 5.6 but still no good at all.
Can you help me on how resolve this problem?
Which PHP Extensions should activate for MOODLE 3.1 ? Since Site Administration link isnt working , I cannot get into MOOODLE Environment to check what modules are not being installed.
