I stumbled across an issue while setting up LDAP for Dokuwiki using the authldap plugin. I run dokuwiki with php7.2 on Ubuntu 18.4 and have windows server 2016 as an active directory controller.
I have several services running that sucessfully use LDAP and i can use the tool "ldapsearch" to contact the Active directory host from the command line of the same machine that runs dokuwiki. Thus I assume that at least the connection should be alright.
So far I narrowed it down to the ldap_connect(server,port) method in the file /lib/plugins/authldap/auth.php
$this->con = #ldap_connect($server, $port);
This call returns -1 . An echo of $server and $port show the correct ip address and port.
I've run out of ideas how to debug this issue and would be very thankful for suggestions.
Thanks & greetings
[Update]
Upon suggestion I removed the silence flag. I could not find changes in any log giving further hints.
I have another log I havent properly looked at:
192.168.4.103 - - [06/Jan/2019:15:51:15 +0000] "POST /dokuwiki/doku.php?id=start&do=login§ok= HTTP/1.0" 403 11344 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36"

For me this looks like there was a sucessful request (http code 200), followed by a 403, suggesting that this action was forbidden.
I assume this is a default answer due to the failed ldap_connect

I am trying to deploy a Laravel app to Heroku with Heroku Postgress. When I deploy however, error debug pages do not seem to load any CSS or JS, making it almost impossible to extract the info I need from the error page effectively. My browser dev tool only shows an error such as
Firefox
Loading failed for the <script> with source “blob:https://...
Chrome
Failed to load resource: the server responded with a status of 500 (Internal Server Error)
The network tool also tells me the only data coming is the HTML from the 500 response in this case.
I have made sure APP_DEBUG is true, APP_ENV is set to development and other essential variables are set. The error page looks fine when running locally and the app works fine when deployed other than the errors I need the debug page for to begin with.
here is the Procfile:
web: vendor/bin/heroku-php-apache2 public/
The console (censored and not including the trace from the error causing the page to be displayed in the first place):
2020-08-12T09:10:18.108148+00:00 app[web.1]: xxx - - [12/Aug/2020:09:10:17 +0000] "GET /xxx/1/xxx/create HTTP/1.1" 500 973197 "https://xxx.herokuapp.com/xxx/1" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:79.0) Gecko/20100101 Firefox/79.0

You may have misconfigured the Procfile and that is causing 500 error.
Attach the Procfile and the error from the console so that we could understand it more.
We have a project running in nginx/php-fpm which is basically a multi-site setup build on Symfony 2.7 and we're working on the next version of the site which is basically adding an another site to the project with some additional features. Just before going live, we needs to make sure everything works fine. So the site was hosted on subdomain.site.com with only internal access.
Basically there are 2 file servers and 2 load balancers with nginx. Load balancers receive the request and direct it to the web servers (where the php-fpm is installed) based on the load.
Now, the problem is the site is very slow, but the same website hosted on the test server is much faster which is having less configuration with multiple projects than the live server. This is what I see from the logs.
Web Server (PHP-FPM):
x.x.x.x - [08/Jan/2019:14:40:33 +0000] GET /app_dev.php/a-sample-url/ 200 Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.102 Safari/537.36 took:14.856s
Load Balancer:
x.x.x.x - [08/Jan/2019:14:40:48 +0000] "GET /app_dev.php/a-sample-url/ HTTP/1.1" 200 38386 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.102 Safari/537.36"
Here you can see that the php-fpm alone is taking 14.856s to execute also I'm unsure about how the logging is happening on the load balancer which is having the later time (not sure if it's the time when it returned response).
The live website is also located on the same server. So I'm doubting if the php-fpm is having a separate configuration for the sub domains.
Hereby I've attached the copy of my php-fpm configuration (excluded default values due to the size).

Any help on this would be highly appreciated.
I am migrating mail servers from OVH/Centos7 to AWS/Amazon Linux; part of my setup uses roundcube webmail.
I have copied all of my config and supporting files from one instance to the other, however can not seem to make the webmail app load as expected. Anything and everything produces a 500 with no useful errors displayed anywhere.
All apps and subdirectories are owned by apache:apache
With the following error config in php.ini
display_errors = On
error_reporting = E_ALL
log_errors = On
This is the ONLY log entry created when navigating to my URL:
w.x.y.z - - [27/Dec/2018:03:56:03 +0000] "GET / HTTP/1.1" 500 - "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36"
The log entry clearly shows the 500, but produces no errors. In addition, the error log file within the roundcube directory is also empty.
The response to the client is empty, just a 500.
$curl https://mail.example.com/
Header is 500:
$curl https://mail.example.com/ --head
HTTP/1.1 500 Internal Server Error
....
If I cd to the roundcube directory and try to evaluate the index, it returns nothing:
$cd /path/to/roundcube
$php index.php
$
I have tried to disable every single roundcube plugin, in config/config.inc.php
$config['plugins'] = array();
Every single other app and web page works, after the transplant; roundcube is the only thing which is throwing 500's and not producing any error messages...
syslog is empty of relevant messages.
What can I possibly do to further investigate why this might be failing?
i can't open one php script on my virtual ubuntu 12.04 lamp server, i tried at an online host and it works fine but at home didn't work.
what i already did:
i intall php 5.4 like the online host
change permisions on folder
change user folder
install php 7 (but the scripts tell php 5.4-5.5)
and i get this error page when i try to open: The requested URL /loja/login was not found on this server.
and the log apache tell :
[client 192.168.0.10] File does not exist: /var/www/script/login
"GET /loja/ HTTP/1.1" 307 769 "-" "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36"

what is wrong on my lamp server? onlines hosts works very well.
the script: https://mega.nz/#!dpskSCDS!vmlxWXVjByV67wv41DO8MqDMPgfjBpxxj_p7uoxmfjQ
Hi please add your php files on your htdocs folder it's /opt/lampp/htdocs
also do this
This will change the ownership of the /opt/lampp/htdocs/ to you:
sudo chown username:groupname /opt/lampp/htdocs
Example : (My username is test and my group name is also test)
sudo chown test:test /opt/lampp htdocs
This will change the folder's permissions to be read, write and executed by you:
sudo chmod 777 /opt/lampp/htdocs
I have a session variable that I set like this:
<?php
$token = md5(uniqid(rand(), true));
session_start();
$_SESSION['token'] = $token;
print $_SESSION['token'];
?>
Then on another page I have this:
<?php
session_start();
print $_SESSION['token'];
?>
The problem is that they don't match. I get two completely different strings. register_globals is off. I did notice that when I set md5(....) to a constant string eg: md5('example') that it works as expected and the two strings match. But that shouldn't matter. Any ideas on what's going on here?

I'm not quite sure how to read that but it looks to me that my file (index.php which I assume is the '/') is being called three times. Am I reading that right? What's going on there?
Completely stupid mistake on my part. I had some empty <img> tags in there that were causing the extra requests. facepalm Sorry everyone, problem solved. Thanks for your help!!
The only solution I can think of is that you are making a second request to the first page without knowing it. You should probably check your apache access log for this second access...
Making a simple request counter would be another solution to check this:
$_SESSION['counter'] = isset($_SESSION['counter'])? $_SESSION['counter'] +1 : 0;
You will notice that every time you revisit the first page, your session variable will change. Since it works for a constant string, 'example', I will assume that you revisit page 1 to view what is stored there.
A fix could be checking to ensure that that session variable is not set before you set it again.
i.e.
<?php
session_start();
if(!empty($_SESSION['token'])){
$token = md5(uniqid(rand(), true));
$_SESSION['token'] = $token;
}
print $_SESSION['token'];
?>
This chunk of code should work as expected.
Looks weird. That first chunk of code that resets the token must have been run again somehow.
