Problems accessing nuBuilder apps via IE11

[armstrs01]

Some of the intended users of a system I am creating use IE11 (with no option to use anything else).

The system has been developed and tested using Chrome.

When I try to log in as a regular user under IE11, I get the following:

IE11_Error.png

I do not get this error when the same user logs in under Chrome.

I can log in as globeadmin under IE11 with no issues.

I have tried adding the home form to the user's access level but this has no effect.

Is there a way to ge around this?

Thanks,
Simon.

Simon,

Is it as soon as they log in or after a while.

Are they logged in a 2 different people at the same time.

It happens as soon as they log in. I have ensured that they are only logged in as one user.

The problem does not occur when I log in as globeadmin.

The message is generated, as far as I can tell, by the nuValidateUser function in nuapi.php.

The following is written to the debug log:


** HOME BUG **

===BACK TRACE====

D:\Bitnami\wampstack-5.4.37-0\apache2\htdocs\nuapi.php - line 415 (nuHomeBug)

D:\Bitnami\wampstack-5.4.37-0\apache2\htdocs\nuapi.php - line 28 (nuValidateUser)



===VARIABLE====

The user has all of the relevant access and can login with no problems using Google Chrome.

Very confusing.

SOLVED!!!

This appears to be a problem with the way IE deals with the $_SESSION data.??

The DNS name of my (dev) server has an underscore '_' in it (I know this is bad practice but I was allocated the name, I didn't select it. )

If I hit the IP address of my server from IE 11, instead of the DNS name, everything works as designed. If I hit the DNS name, the error returns.

I'm having the DNS name of my server changed, as I type this...
