conflict with another plugin

hello and thank you for your work!
I have an issue with the another plugin that i’m using called LifterLMS. Basically, i cannot access the editing page for one of my online courses, where I use your quizzes. I contacted their tech support and they said the issue might be related to QTL and instructed me to contact you.
I hereby quote what i was answered at LifterLMS.

“It appears that the builder is failing because a plugin, I think “Quiz Tool Lite”, is outputting a buch of custom css and scripts during our AJAX calls.

It looks like the issue is that the plugin echos these styles and scripts instead of returning them. This will work just fine during actual rendering but will cause issues when the content is not supposed to be displayed.

I’ve attached a screencap of the content being output by the plugin which is breaking our AJAX call.

Disabling this plugin should resolve the issue, but that wouldn’t allow you to continue using it! I’d recommend reaching out to the plugin devs for some assistance here. The issues all come from their class “qtl_quiz_draw”.

Do you have an email where I can attach the screencap?
Do you seen any ways we can correct the issue?
It used to work alright earlier.
Thank you in advance.
