Hi Ziyan,

After looking more into this error message. It looks like it is not related to the problem I'm having with forms. I am getting "Page Unresponsive". We never had this issue after we upgraded our LF forms to 10.4, but now it is back just like the issue were having with the Previous LF forms version.

I'm not sure why all of sudden were encountering this error. The forms application is just loading just about over 20 rows of data from SQL database.

Hopefully you can help solve this issue.

Thank you!

Which version of Forms are you using? Which page is giving the error?

Previously we've heard that loading large list of unassigned task will have similar issue in 10.4.1. Not sure whether it is same as your problem.

Laserfiche Forms Professional Version 10.4.5.282

It is working in chrome incognito mode. Any idea why it is working in that mode ?
