I have Vik Events (https://extensionsforjoomla.com/components-modules/vik-events-e4j) implemented on my site.

Since it was last used in December 15, I’ve since purchased and installed Admin Tools. Unfortunately Admin Tools appears to be blocking IPN messages from PayPal

PayPal Instant Payment Notification Warning E-mail:
Please check your server that handles PayPal Instant Payment Notifications (IPN). Instant Payment Notifications sent to the following URL(s) are failing:
http://www.chipperfieldtheatregroup.com/index.php?option=com_vikevents&task=notifypayment&oid=357
http://www.chipperfieldtheatregroup.com/index.php?option=com_vikevents&task=notifypayment&oid=358

As a consequence orders are not being upgraded from Pending to Confirmed (I’ve been doing this manually through the backend)

My hosting company asked me to disable Admin Tools (as you have also advised in previous support Tickets).
They had previously replaced my .htaccess file with the standard distribution without effect.

I have also set PayPal button language encoding to "UTF-8"

Disabling Admin Tools resolves the issue.

Please advise.

Regards

Stuart

Sorry - I should have added that Security Exceptions Log is on - but I'm not getting any logs.

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.
