Downloads links are in an infinite redirect loop

[paperweight]

When a logged-in user clicks to download a link, the link looks like this:

https://website.com/whmcs/dl.php?type=d&id=20

 

But after the click, the browser says there is a redirect loop and the process can not be completed.

 

This is the first time I activated downloads on my site, soi I never witnessed this problem before. Any ideas what this could be causing the problem?

Hi,

What are your Setup > General Settings > WHMCS System URL and WHMCS SSL System URL settings?

This behaviour could suggest they're configured incorrectly. The first should begin http:// and the second should be blank or being http:// if you have your own SSL certificate installed.

Hi John, many thanks for your help~

WHMCS System URL: https:///whmcs.mysite.com

WHMCS SSL System URL: [blank]

 

Above is what is currently in the fields. I do have SSL installed.

 

For the "WHMCS SSL System URL" I tried adding https:///whmcs.mysite.com but when I click "Save Changes" the resulting page makes that info disappear, so it is blank again like above.

 

If I change the "WHMCS SSL System URL" to http:///whmcs.mysite.com (I remove the 's' from http) then after I "save Changes" it remains there as http:///whmcs.mysite.com but the doanloads still have the redirect loop, so it appears to not help.

 

Any other thoughts on a fix for this malady?

Try it with 2 slashes instead of 3

WHMCS System URL: http://whmcs.mysite.com

WHMCS SSL System URL: https://whmcs.mysite.com

 

You should never put the same URL into both fields. This message can also show as: "The page isn't redirecting properly"

hehe, thanks. the 3 slashes was a typo I made in this forum~ Doesn't 3 slashes get me to the webpage faster than 2

 

Ok, but I do have SSL installed and I want to force users to visit that, so why would I not have the https in both fields? I mean, for the "WHMCS System URL" I want users to visit the https version of the entire site so I am confused about what goes where. I realize it probably appears simple but it is still confusing~~

 

I am checking htaccess as well since I recently added a 404 Error addon that maybe is impacting this. I will work on it today.

You should never put the same URL into both fields. This will show message: "The page isn't redirecting properly".

 

You don't want to force users to visit that. WHMCS will switch between HTTP and HTTPS.

Ok understand

 

I appreciate all the tips. htaccess appears to be the culprit and it is being fixed now.

Ok, good news and bad news:

 

Good news is I fixed the problem. It was a combination of the incorrect URLs in the System URLs and the htaccess errors. MY downloads now work.

 

Bad news is that I now do not have SSL forced on the installation. I previously had forced https on the entire installation using this in the htacess:

 

# This rewrites URLs to force https on all requests to whmcs

RewriteEngine On

RewriteCond %{HTTPS} off

RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

 

RewriteCond %{HTTPS} off

RewriteCond %{REQUEST_URI} !^/dl.php [NC]

RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

 

RewriteCond %{HTTPS} on

RewriteCond %{REQUEST_URI} ^/dl.php [NC]

RewriteRule (.*) http://%{HTTP_HOST}%{REQUEST_URI}

 

RewriteEngine On

RewriteCond %{SERVER_PORT} 80

RewriteRule ^(.*)$ $1 [R,L]

 

However, now I removed that. I need to force SSL on the entire installation on all the pages because of the requirements of my users. I know this is taxing on the server, but it's important for my clients. Any idea how I can now force https throughout?

 

Here are also my current URL settings:

WHMCS System URL: http://whmcs.mysite.com

WHMCS SSL System URL: https://whmcs.mysite.com

 

I appreciate all your great feedback to help me.

adding the URL settings too

[Bubka3]

You could do this:

 

WHMCS System URL: https://whmcs.mysite.com

WHMCS SSL System URL: [blank]

Thanks @Bubka3, but that is what I originally had. It does work, but then other things break.

 

I think I need to hire someone to take a look at this. Will check into that and let you know how I fare~

[paperweight]

hehe, that was my typo on this forum, but it is 2 slashes in WHMCS~

[Bubka3]

Yes, but you also had it in SSL field, not just the non-SSL field, and you also had a .htaccess. If you put the SSL url in the non-SSL url field, it should work fine. No need to add it to SSL field and cause a double redirect.
