We are developing a website on a server, but we have a problem. One of our developers started getting a Internal Server Error (500) when he submits a form. It only happens with forms that use
post as a method. The apache error is:
Handler for x-httpd-php5 returned invalid result code 70007, referer: http://example.com/page
The problem only occurs on his laptop (and only his laptop so far), regardless of the browser he uses and regardless of the WiFi network he is connected to (different ISP each time). He tried a system restore of his laptop without any luck. He built a VM on his laptop with Windows 8 and is able to post forms within the VM. He is able to submit post forms on other websites hosted on the same server. He is not using a proxy or a firewall on his laptop that can cause the error. We cleared the server and added a single test.php with just a form and a submit button, it gives the same error.
The server uses the following:
- CentOS release 6.2 (Final)
- Apache 2.2.21
- DirectAdmin 1.41.1
- Php 5.3.22
Does anyone have any idea what might be causing this error? The fact that only his laptop has the problem suggests that it is a client-side problem. We are however struggeling to find anything on the laptop that could be causing this error.
-edit- Rebooting the laptop in safe-mode allows the developer to submit forms again. It seems to be a client-side problem. More ideas as to what might be causing this problem?
