Apache on Linux to IIS 10 on Windows Server 2016 - Blank Page

[jasondogor]

Hello Guys, after a backup restore from Apache to IIS, the site loads correctly, the database connection works fine and the main page and the login administrator page are accesible.

However, when i tried to access with the administrator account, appears HTTP error 500 in different browsers.
I've been searching solutions for two days. In some threads people suggest enable $error_reporting to development and enable debugging on the configuration.php file. After that, i tried to access again and appears a blank page, there is no log registered.

Another think that i checked is the htaccess file. I imported succesfully in IIS using the URL Rewrite component on IIS.

I tried again restore the site on RedHat Server with apache and it works without problems.

It is possible a related problem with the OS version? or PHP Version? or there is a possible configuration that i missed during the restore process? Thanks in advance guys!

On IIS you use the web.config.txt file and not .htaccess

Done, the URL rewrite component on IIS turn the rules in .htaccess file into rules inside of web.config file. But the problem persists.

I would try using the default web.config file that comes with joomla rather than importing from htaccess,they are very different.

This is what it should look like.

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<location path=".">
<system.webServer>
<directoryBrowse enabled="false" />
<rewrite>
<rules>
<rule name="Joomla! Rule 1" stopProcessing="true">
<match url="^(.*)$" ignoreCase="false" />
<conditions logicalGrouping="MatchAny">
<add input="{QUERY_STRING}" pattern="base64_encode[^(]*\([^)]*\)" ignoreCase="false" />
<add input="{QUERY_STRING}" pattern="(>|%3C)([^s]*s)+cript.*(<|%3E)" />
<add input="{QUERY_STRING}" pattern="GLOBALS(=|\[|\%[0-9A-Z]{0,2})" ignoreCase="false" />
<add input="{QUERY_STRING}" pattern="_REQUEST(=|\[|\%[0-9A-Z]{0,2})" ignoreCase="false" />
</conditions>
<action type="CustomResponse" url="index.php" statusCode="403" statusReason="Forbidden" statusDescription="Forbidden" />
</rule>
<rule name="Joomla! Rule 2">
<match url="(.*)" ignoreCase="false" />
<conditions logicalGrouping="MatchAll">
<add input="{URL}" pattern="^/index.php" ignoreCase="true" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" />
</conditions>
<action type="Rewrite" url="index.php" />
</rule>
</rules>
</rewrite>
</system.webServer>
</location>
</configuration>

Recently follow your instructions, restarting the IIS service, however the problem persists. I used the web.config file of the package version downloaded directly from Joomla.

Don't know then. Often with IIS and joomla permissions play a role but that's a guess.Good luck

Thanks, definitely i need luck to solve this. There is no enough official documentation to set permissions on Folders using IIS.

If you have any additional idea, please let me know!

I found the solution. The problem was related with a component called JMApMyLDAP authentication. I disabled it directly from the database and the login works. Now i Need to configure SSO
Thanks for your help.
