Images Suddenly Stopped Displaying

KevinTheJedi sorry, i will try to make it clear attachment is not in same path which is resolved from database instead of big C in folder name there is small c on filesystem could this be the problem ?

KevinTheJedi

It all depends on what the key from the db is and the IIS setup. Not all setups are the same so yours could very well not be case sensitive. I just know the majority of IIS setups that I’ve dealt with are. Anyways, the key from the db is always the correct casing. So whatever the first character of the key in the db is should be the folder it’s stored in.

Cheers.

KevinTheJedi Hi, I was able to get it working again by starting from scratch (even WM) initializing new server not just DB an reinstalling server how ever after 12 days same error appeared again.

Any idea what can be tried next ?

Is using windows I would simply suggest moving to Linux.

Cheers.

KevinTheJedi this is not possible in our Sec Enviroment

gamerclassn7

EDIT: Files can be accessed on File System and also in outgoing email and just not in WEB

KevinTheJedi

Then without much more information or access to your system I cannot really further assist. I don’t have too much experience with windows servers so I’m not going to be of too much help unless I have access to your system (which I can’t do unless you go through our support services) or if you provide enough debug information.

Cheers.

KevinTheJedi As i stated i can provide what ever you want, but that is that is problem there is nothing in logs :/

KevinTheJedi

I am not talking about logs; I am talking about actually debugging. Like adding debug statements to the code at various points to see where it’s failing. Do you have a firewall, antivirus, browser extensions, etc.? Can you access the site from home on a home computer to see if issue persists there?

Cheers.

gamerclassn7

KevinTheJedi no i cannot access it outside network, it is only accessible inside local network, how ever it is not working on any computer not localhost. If you have any suggestion where to add debug prints i can do it right away 🙂 just send me a file and line and what to add 🙂

KevinTheJedi

You would simply need to follow the file retrieval pipeline. Starts with file.php and goes from there. For example since you are talking about inline images it would be going to the display() function of AttachmentFile class. There I would debug to see if gd extension is loaded to see if it goes through the if() statement. If not then it will immediately go to the sendData() function. This will call open() to get the instance and then call passthru() from the plugin.

Cheers.

gamerclassn7

KevinTheJedi I will try to do it right now

gamerclassn7

Which variable should i dump inside display () ?

gamerclassn7

i added thi debug lines

but nothing happened :/

KevinTheJedi

gamerclassn7

It would be output in the HTTP response. I would personally use error_log() instead so that you can simply tail the error logs whilst making the requests.

Cheers.

gamerclassn7

KevinTheJedi on it

gamerclassn7

KevinTheJedi No log Either

KevinTheJedi

gamerclassn7

Then go further back and start at the beginning:

Cheers.

gamerclassn7

KevinTheJedi
finally some output 🙂 GD is loaded and url is called

KevinTheJedi

gamerclassn7

Where was that though..? From file.php or from the original include/class.file.php?

Cheers.

gamerclassn7

something is even hitting
send data part

KevinTheJedi

gamerclassn7

Okay, so it's hitting sendData() so then check passthru() which will be at the plugin level. For this you will need to unpack the plugin so you can modify the core files. This means you will also need to go to the database, go to the _plugin table, find the record for the FS plugin, set the install_path to include/storage-fs (just remove the .phar from the existing value), and set isphar to 0. At that point you can go modify the core plugin files and add your debug to the passthru() function within the plugin.

Cheers.
