Getting error message during install process

Many thanks in advance
i have read that article and have done these steps and replaced web.config  customerror mode tag as below

<customErrors mode="Off" />
  
<!--    <customErrors mode="RemoteOnly" defaultRedirect="ErrorPage.htm">
      <error statusCode="403" redirect="BannedAddress.htm"/>
      <error statusCode="404" redirect="FileNotFound.htm"/>
    </customErrors>
-->

and have also done like that as below

<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
    </system.web>
</configuration>

and have also tried the code change as below

<customErrors mode="Off" />
  
<!--    <customErrors mode="RemoteOnly" mycustompage.htm">
      <error statusCode="403" redirect="BannedAddress.htm"/>
      <error statusCode="404" redirect="FileNotFound.htm"/>
    </customErrors>
-->



still i get same error message   at    http://www.wholesalesonly.com/Install/install.aspx

please advise

try reading this first

Thanks i have read this article already but it does not solve the issue even i have installed a fresh installation, please advise whats wrong and where

its impossible to know the issue because we are getting no error data

we are getting no error data because cutom errors need to be turned off in the web.config file

once you turn them off, you will still get an error but it will be a meaningful one which you can post here - then we can help you

whatever you are doing, it is not turning off custom errors so either you are not saving web.config or you are doing something wrong. Have you downloaded the software or have you done a web install? if you are running it on a hosted server, are you editing the web.config file which is on the server? sorry for such simple questions.



this already exists in the web.config file when you download it:

<customErrors mode="RemoteOnly" defaultRedirect="ErrorPage.htm">
      <error statusCode="403" redirect="BannedAddress.htm"/>
      <error statusCode="404" redirect="FileNotFound.htm"/>
    </customErrors>

are you replacing it ?  or just adding


<customErrors mode="Off" />
  
<!--    <customErrors mode="RemoteOnly" mycustompage.htm">
      <error statusCode="403" redirect="BannedAddress.htm"/>
      <error statusCode="404" redirect="FileNotFound.htm"/>
    </customErrors>
-->

Thanks i have done the following change to web.config file on my hostings erver, i have not added the code below but have replaced it, this is the code which i replaced it from the download file and then i saved the file on my hosting server with this and at this point my hosting server shows this change in web.config

<customErrors mode="Off"/>
