I use to be able to view the conjunction chart but not anytime I click it, it just blinks for an instance and wont stay up. If I view it through the "view terms" section it works fine, but If I'm doing a quiz or study it will just pop up real quick.
I have made some changes to a FEW of the popups on renshuu, slowly introducing a full rewrite of the popups.
I cannot yet replicate this, so let me ask you a few more questions. If you refresh the page on the browser, and then try it again, will the issue persist? If not, then that suggests something else is happening earlier that is causing the problem to pop up later on.
I'm not sure if you did something on your side, but now it's working just fine. It's been like this for a week or so now, but now it seems to be just fine, so not sure what was causing it. Will update if It ends up happening again.
