Just installed MultimediaViewer: it works great but if I click on X button, if I press Esc or even if I go back one page, the browser just shows an empty black page.
I fired up Chrome's Developer tool and I get the Console error reported below. I should mention I am using MediaWiki 1.26 and I tried the snapshot for both 1.27 and 1.30, as there isn't one specific for 1.26.
I also tried the require_once() loading modus rather than using wfLoadExtension() but it doesn't seem to make a difference.
I'm not into php enough to understand what's going on. Is there an incompatibility with the SimpleTooltip extension?
