Cannot Fix Internal Server Error 500

[wilxp]

My problems are as such.

First installation attempt:
-Got the error when i use the filemanager in ispcp on a remote machine.

Second installation attempt:
-Got the error when i uploaded postnuke CMS, but works fine when i upload Wordpress.
-Filemanager still got error

Third installation attempt:
-All php scripts seem to be in error.
-Filemanager still got error

I am using Ubuntu 8.10. I intend to do a complete removal and re-installation again. Any thing that i need to take note of?

When i do setup, do i choose the default "admin.{serverhost}" or simply use {serverhost}? Do i choose fcgi or fastcgi? Are they the same?

Thank you.

fcgi & fastcgi is using the same program which is php-cgi but different method, both have + and -, better read which one you prefer. It will be helpful for community to help you if you can provide info about what kind of error you encounter. Right know i can only guess for 2nd installation probably becouse php restriction ( php.ini configuration which control security )

[sci2tech]

You must use last trunk. In RC7 there is no support for Ubuntu 8.10.

Altough this is an old thread I also get 500 internal server error message.

The IspCP works fine but calling php files on domains and subdomains leads to 500 internal server error messages.

I checked apache logs and logs of the domain but nothing there. Any ideas or suggestions where to start looking what's going wrong?

thanks for your help!

This is a never ending problem.
I have several pages running into the Internal server Error 500.

Ex. at http://www.n3xt-gaming.com - When I activate:
$autoresize=1;

if($autoresize==1) {

preg_match_all("|(\[img\])(.*)(\[\/img\])|i", $content, $imgtags, PREG_SET_ORDER);
foreach($imgtags as $teil) {
$content = str_replace('[IMG]', '[img]', $content);
$content = str_replace('[/IMG]', '[/img]', $content);
$picinfo = getimagesize($teil[2]);
switch($picinfo[2]) {
case 1: $format = "gif"; break;
case 2: $format = "jpeg"; break;
}
if(!$picsize_l) $size_l = "9999"; else $size_l=$picsize_l;
if(!$picsize_h) $size_h = "9999"; else $size_h=$picsize_h;
if($picinfo[0] > $size_l OR $picinfo[1] > $size_h) $content = str_replace('[img]'.$teil[2].'[/img]', '[url='.$teil[2].']<img src="'.$teil[2].'" b$
elseif($picinfo[0] > (2*$size_l) OR $picinfo[1] > (2*$size_h)) $content = str_replace('[img]'.$teil[2].'[/img]', '[url='.$teil[2].'][b]Large pict$
else {
$content = str_replace('[img]'.$teil[2].'[/img]', '<img src="'.$teil[2].'" border="0">', $content);
}
}
}
else $content = preg_replace("#\[img\](.*?)\[/img\]#si", "<img src=\"\\1\" border=\"0\">", $content);

return $content;

}

The page is not able to load and causes the internal server error 500.

When I set $autoresize=1; to $autoresize=0; the page works fine - The function is very important to that community, since else their users will be able to post very large images which causes the page to look weird.

Same as at my own blog running wordpress, the page only loads after you retry a few times.

[balistof]

it just found following warning/error log entry in "/var/log/apache2/users/default-error.log"

[Fri Jan 02 17:47:58 2009] [warn] (104)Connection reset by peer: mod_fcgid: read data from fastcgi server error.

any ideas? I have constantly the "500 internal server problem" and was never able to run a php script

[sci2tech]

Possible cause:
php version <=5.2.0 (default for etch. Solution update php)
Mismatch between associated uid/gid for script, containing folder or /var/www/fcgi/domain.tld folder or content. Solution: correct uid/gid.
If limited resources or script take time to execute, increase for fcgid IPCConnectTimeout value (in /etc/apache2/mods-available/fcgid_ispcp.conf). Try switch to ispcp_fastcgi/ispcp_fcgid and see if problem persist.
Test if your configuration file template against trunk (maybe problem was corrected).

My Settings:

Installation:

Answer: Installed php:

sci2tech:Mismatch between associated uid/gid for script, containing folder or /var/www/fcgi/domain.tld folder or content. Solution: correct uid/gid.

Answer: All uid/gid's are correct, else you'll get the internal server error 500 permanent

------------------

sci2tech:If limited resources or script take time to execute, increase for fcgid IPCConnectTimeout value (in /etc/apache2/mods-available/fcgid_ispcp.conf). Try switch to ispcp_fastcgi/ispcp_fcgid and see if problem persist.

<IfModule mod_fcgid.c>
AddHandler fcgid-script .php .php5
SocketPath /var/lib/apache2/fcgid/sock
IPCConnectTimeout 600
</IfModule>


And since it's already the latest trunk, it's probably not fixed. <-- That sentense is not meant bad

[c0urier]

Well mine certainly worked after the nightly backup? Strange stuff - No more 500 errors!
