Hello, I am upgrading a client's site's moodle from 3.3+ to 3.5.9 prior to a PHP version change taking place on their host tomorrow (7.1 to 7.2). I am able to get past the initial check with everything clear except a suggestion about xmlrpc, but still meeting the minimum requirements. When I press "continue" to what should be the plugin check page I get HTTP error 500...:
This page isn’t working
What would cause the plugin check page to not display on upgrade? I turned on developer debugging and am not getting any more detailed error messages.
How can I fix this?
Thanks for any advice
