Broken help links in Variables tab #13805

ibennetch opened this issue Nov 9, 2017 · 2 comments


Copy link

commented Nov 9, 2017

Steps to reproduce

  1. Enter the "Variables" tab from the main page
  2. Click any help link; the question mark icon at the top of the page or any linked text like 'datadir'

Expected behaviour

Individual variables should have the help icon behind them, I think. Regardless, the link should open correctly.

Actual behaviour

( ! ) Fatal error: Call to a member function getDisplay() on null in /var/www/pma-dev/fork/libraries/classes/Response.php on line 266

I too have this issue, however on any page and with older commits. Perhaps an issue with a dependency?

Apparently it's broken since 60c1b32.

Remove usage of $GLOBALS['userlink']
The links are internal to DatabaseInterface and user link is default.
