Error 500 about ifm

[misterunknown]

Do you have access to the server logs? "general error"s mostly indicates a server configuration problem.

apache_error_log is empty, no errors connected to ifm. In access_log i see the requery and replay with err 500. No other clue.

[misterunknown]

Well, that's weird. Did you test already if PHP runs correctly? It's also important that you have the correct version installed. The IFM needs at least PHP 5.4.

Also important:

• Does the webserver have at least read access to the filesystem?
• Can you maybe post an anonymized part of your access log?

[jezikk82]

PHP work correctly, I test few of php file manager over the w-end and only IFM faild to work.
I have PHP 5.5.11.
Scipts have read acces to filesystem

Access_log:

xxxxxxxx - - [15/Jun/2014:12:58:42 +0200] "GET /xxxx/ifm.php HTTP/1.1" 500 - "http://xxxxx/" "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.114 Safari/537.36" /xxxxxxxx/ifm.php 4530 pid=25146 id=U5bk4lZv8QsAADJvvnkAAADG

OK, I found the problematic functions:

• posix_getpwuid
• posix_getgrgid

When switched off showing this info IFM is working.
On production serwer it doent return anything and cause errors.

[misterunknown]

Well, yeah, that functions don't work on windows systems. I'll write a hint in the documentation and add a workaround for this issue to the todo list.

Is your production system also a windows system? What about the server logs on that machine?

[jezikk82]

Production is Linux + Apache.
In the log was no info at all.

[misterunknown]

Hm. Which distribution do you use? On a linux machine you can send a request to the API of the IFM. Maybe this shows some error information:

curl --data "api=getFiles" yourhostname/yourpath/ifm.php

If you are using Apache Basic Authentication:

curl -u user:password --data "api=getFiles" yourhostname/yourpath/ifm.php

This should return a JSON-parsable string with all your files and directories. If it returns nothing you can try to enable PHPs error reporting at the beginning of the script right after the PHP-Tag:

<?php
error_reporting(E_ALL);

None of this get any output, just blank page and in firebug i see it's error 500.
When i switch off this 2 option it works.

Hi. I just updated the IFM. I implemented a check for this posix_* functions. If they are not available it shows not a user or group name but the user or group id. Unfortunately it is not possible to resolve the user name on windows systems. I hope that your problems are solved now.

[jezikk82]

i'll check it and let you know.

[misterunknown]

I guess this issue can be closed.
