Test FSOCKENOPEN causes 500 error

[Sonya]

Trying to install CMS Made Simple on customer hosting, I have got error 500 on step 2 (checking environment settings).

While debugging I have figured out that the function testRemoteFile() in /lib/test.functions.php causes it. The problem is on this special hosting is that if the call below fails, it returns NULL and not FALSE as described in docs http://de.php.net/manual/en/function.fsockopen.php

Code: Select all

@fsockopen($scheme . $url_info['host'], $port, $errno, $errstr, $timeout);
if(false !== $handle)
	{

In the second line the script checks if $handle is false and the installation is aborted with 500 error, since $handle is not FALSE but NULL. I have replaced the condition with if(false != $handle) and the installation was successful. Module Manager does not work due to the remote check failure (as expected), but all other fuctions are OK.

Server settings from admin panel immediately after installation

Can someone see if it worth to correct the issue in the core? Thank you!

Sorry but I read FALSE and not NULL
Can you test with a var_dump($handle) for check your exact return?

Hello alby,

yes, it is NULL and not FALSE. I have checked it with var_dump($handle). I think it is due to disabled allow_url_open (it is sure disabled, I have asked).

Additionally, in line 1161

Code: Select all

getTestReturn($test, $required, '', '', lang('connection_error'));

The message, that Module Manager will not work, does not appear. I think, it should be:

Code: Select all

getTestReturn($test, $required, lang('connection_error'), '', lang('connection_error'));

Thank you!

Sonya, can you look your server error logs? 500 report always in http logs

Unfortunately not I have no access to the logs. It's a low budget hosting
