Random "deleted" box on a page?

Ask the Community Get Answers

I’m trying to troubleshoot an issue reported by a student in our Knack app.

She is intermittently seeing a small black box with the word “deleted” displayed on her form pages (see screenshot attached, top left of image). She is using Chrome, and I have been unable to reproduce the issue myself.

Additional details:

  • I use the KTL library throughout my app

  • The page is targeted by KTL using:

    _cls=[pagewidth], [ktlTarget, scene]

  • No other KTL keywords are used on the page.

  • I have not been able to reproduce the issue as an admin or impersonating the student.

I’m wondering if anyone has seen something similar before. Does this look like something that could be related to KTL/Discovery Hub, or is it more likely a Knack rendering issue or browser-specific issue?

Any insight or troubleshooting suggestions would be appreciated. Thanks!

@NormandDefayette_CortexRD I’m tagging you in case this is a KTL thing?

@Leah,

Did you try disabling the KTL?

This procedure should give you a clear answer, using Bypass KTL:

No need to remove the code. Just disable it in your browser instance, not all users.

It looks like that Deleted text is showing as a tooltip.

can you open the page in Incognito mode and check ?

as you are using Editor below, which might track changes and can show tooltip based on that.

Thanks! Unfortunately I can’t replicate the issue, and it seems to have gone away on its own so my student is no longer able to see it either. I have some ideas to explore if it pops up again.
