Hello, we are experiencing some issues with J2Store when trying to connect to the Barclays ePDQ system for payments. The behaviour being seen is as follows:

  • We can make a purchase and make payment via Barclays with no issues.
  • The site shows an order and Barclays receive the payment with no errors.
  • Barclays system then returns the user to the site on a URL we provide and this is supposed to set the payment on the order to confirmed.
  • Our admin are at Barclays is showing that the user has been returned to the site but that the site has not responded and.a 403 has been generated.
  • if we put the return URL from the Barclays errror message into a browser it does not generate a 403 and the order status is set to confirmed.
  • Barclays offer the return of the purchase details as a post or get we have tried both with the same results.

I have contacted the hosting supplier and they are saying it’s the site’s firewall…`I’m not inclined to believe them as `I use your software on all sites and this is the first issue of this sort that `I have seen.

Can you steer me towards where `I need to look please?

 

Thanks

Hello,

Let's make sure that the problem is indeed caused by Admin Tools. In order to do so, try the following:

1. Try setting the Error Reporting level in your Global Configuration to "None". Many errors are caused by harmless PHP Notices and Warnings being output to the browser, breaking anything which requires HTTP header manipulation such as Joomla!'s session management, AJAX calls and download systems.

2. Try to replicate the issue after disabling the "System - Admin Tools" plugin. If you can still replicate the issue, it is not caused by Admin Tools. Disabling that plugin means that Admin Tools code (including the Web Application Firewall) is not running on your site.

3. If you suspect an issue with the .htaccess file, replace its contents with the contents of the stock htaccess.txt file shipped with every version of Joomla!. If you are on GoDaddy please wait for 1-30 minutes for the changes to be effective. Then, retry loading the problem page. If you can still reproduce the error, then it is not caused by .htaccess Maker.

If doing any of the above resulted in the issue still occurring, it's not related with Admin Tools and we can't help you. If doing any of the above did stop the issue from occurring, we'll have to do some troubleshooting.

First go to Admin Tools, Web Application Firewall, Configure WAF. Make sure "Log security exceptions" is set to Yes; if it's not, set it to Yes and click on Save. Now try reproducing your issue. Immediately after that, please go to Admin Tools, Web Application Firewall, Security Exceptions Log. The latest log entry at the top should have the date and time of when the issue occurred. Please copy the Reason and Target URL here so that we can further help you.

If, however, you do not see a log entry, or the Date and/or IP address do not match your last access, this problem is not caused by Admin Tools' WAF. In this case, you will have to do some .htaccess troubleshooting. You may need to read the general .htaccess troubleshooting page, as well as the page on finding out necessary .htaccess exceptions.

Hello Davide,

thanks for the response.

I checked item one in your list and the error reporting was already switched off.

I disabled the Admin Tools system plugin and retested the purchase process, the error was still present.

I switched out the htaccess file and retested the purchase process, the error was still present.

It would appear that I need to speak with the hosting provider?

 

Cheers

Yes, maybe they would have more info about the issue. I can only tell you that Admin Tools is not involved in the process, since by replacing the .htaccess file with Joomla default one and disabling Admin Tools plugin will effectively turn off our software for good.
