Forms 10 error [LFF502-UnexpectedError] when submitting

Forms Version 10
Updated August 28, 2017
asked on March 31, 2016

Hello,

I've just install LFForms 10 and make a form but when I try to submit it I get an error 500 and this error code on the page : [LFF502-UnexpectedError].

FYI, I run it on a virtual box under Win7 pro x86. I've already try to do the LF Forms update1, restart the FormsAppPool, reboot the virtual box, nothing change.

 

Regards.

Hi Alexander,

 

I have the same bug and tried to find the variable with no name but unsuccess. We are using french world ; if we our variable's name have accent (é,à,ê,...) can we have the same error?

 

 

Hum... I make my own test, looks like accent is not a problem.

Please check the LFForms event log on the server to see if there are any additional details regarding the error.

In the Windows Event Viewer, it's at Applications and Services Logs > LFForms
