Constant pop-up "Error occured while clearing Browser credentials."

glen4cindy — Mon, 05 Jul 2021 13:48:34 GMT

While configuring different options within the web interface of an autonomous configured Cisco 1142 AP, every few minutes I get this pop-up that interrupts the configuration process.

"ERROR:

Error occured while clearing Browser credentials."

This pop-up happens irrespective of whatever computer or browser I am using to configure the AP, and has actually happened on 3 different versions of the software I have had on the AP's.

Thanks in advance.

Buenos dias,

Hey Glen,

This issue looks pretty new to me. However, as u saw the issue on multiple computers with multiple browsers and multiple AP codes , I guess that there might be some configuration on the AP , which has not changed over the codes. Multiple browsers or computers can not be bad.

>> The computers that you tested .. were they corporate ones or personal ? I mean , are they configured with a corporate image and group policies ? In that case, the browsers will have the same problematic policy pushed across.

>> Ca you try to get the entire config from the AP ?

Cheers,

Manish

It's because of pre-historic javascript in the web UI attempting to log the user out in a way that does not work on modern browsers.

The solution is to modify config.js, which can easily be re-loaded via TFTP. If anyone wants this fix - message me.

G'Day Matthew ~ I suspect a few people will be having this one. Can you please post the modifications to config.js?

Many thanks

Rus

First get a modified config.js

Below is mine from 12.4:

Before:

http://xpander.mattmillman.com/files/linked/config.js

After:

http://xpander.mattmillman.com/files/linked/config.new.js

You most likely can't use this on other releases. Instead compare my before and after, and make those changes

Or take a look at this:

http://xpander.mattmillman.com/files/linked/configjsfix.png

You'll find those pieces of code in your config.js, then simply make those same changes.

You can get your config.js by extracting the release tar file with 7-zip

CD into the '1' directory (which is under <release>/html/level/

ap#cd c1250-k9w7-mx.124-25d.JA2 <-- your release directory will have a different name
ap#cd html
ap#cd level
ap#cd 1
ap#

Now overwrite the config.js with the patched version

ap# copy tftp://yourserver/config.js flash:

Done

I know this is an older thread, but, among older things, this pandemic and a lot of WFM has had me back to working on other projects.

I finally figured out how to fix this and it worked beautifully!

Thanks Matthew!!
