Too many redirects ONLY in IOS?

Question

This site works fine everywhere except in IOS. http://www.pepedivecenter.com.

• It works in Windows with Firefox, Chrome or IE.
• It works in OSX with Safari or Chrome
• It works in Android phones
• BUT, it does not work in IOS (iPhone or iPad) using Chrome or Safari!

When I try to open the site in an iPad or an IPhone with Chrome or Safari I get a TOO MANY REDIRECTS error.

The web.config is pretty clean:

    <?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <handlers>
            <remove name="PHP_via_FastCGI" />
            <add name="PHP_via_FastCGI" path="*.php" verb="*" modules="FastCgiModule" scriptProcessor="C:\php\php-cgi.exe|-d open_basedir='D:\XVRT\pepedivecenter.com\Html;D:\XVRT\pepedivecenter.com\html\new'" resourceType="File" requireAccess="Script" />
        </handlers>
        <security>
            <ipSecurity allowUnlisted="true">
            </ipSecurity>
        </security>
        <staticContent>
            <remove fileExtension=".htm" />
            <remove fileExtension=".html" />
            <mimeMap fileExtension=".html" mimeType="text/html" />
            <mimeMap fileExtension=".htm" mimeType="text/html" />
        </staticContent>

    </system.webServer>
</configuration>

I tried enabling and disabling the friendly urls, the site is running under IIS so I tried several configurations with web.config

I cleaned joomla's cache and redirects.

I cleaned the browsers cache and cookies.

I updated everything to the last version (joomla 3.6.5) but the problem continues.

How can I troubleshoot this problem? any ideas?

tks!

Answer 1

I found a workaround.
The problem was caused by the Joomla plugin "System - Language Filter". I disabled this plugin and now the site works in IOS.
