Thats quite strange, which browser is he using? can he maybe try Chrome?


That link doesn't work (I get: Your connection is not private Attackers might be trying to steal your information from help.freshphone.co.za (for example, passwords, messages, or credit cards). Learn more) and I can't find your post.

I tried Chrome and I now get:


Server Error in '/' Application.

Hi John,


I can log into Seans profile on my side. Did you try using another broswer to see if the error message appears. I would also try clearing all your cookies for the Freshphone TMS. 


Thank you. 

My detailed response about 5 hours ago seems to have disappeared. Is it somewhere else?

I deleted cookies and tried on Firefox, Chrome and Edge. I get this far:

but when I click on open I get:

Unable to load section, try to reload the TMS Tab by clicking on its header.


If I click "back" I get

Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.Cookies value was detected from the client (EuphoriaUserAccount18258="...ame=Sean O&#39Shaugnessy&PbxMa...").

Source Error:

The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:

1. Add a "Debug=true" directive at the top of the file that generated the error. Example:

  <%@ Page Language="C#" Debug="true" %>

or:

2) Add the following section to the configuration file of your application:

<configuration>
   <system.web>
       <compilation debug="true"/>
   </system.web>
</configuration>

Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.

Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.

This problem is now 10 days old. My friend is not able to access his account.


Hi John,


does the issue look like this?


Yes. It is similar in all browsers.

Hi John,


Please advise if the issue still persists, the problem existed with the apostrophe in the surname. We have to fix it still but for now it should work. 

That works. Thanks!

Hi John, 


Thank you.
