Problem with bigger files?

did you try to increase your max upload size ? in php.ini

You can try to upload some other file from your site without using Cobalt and check if ti is issue of the server or component.

Sven,

i just made a test with a 48MB PDF file. Works quite well here using Cobalt 7 and latest upload field.

I uploaded with a Cobalt application already around 235K documents with file sizes up to 80MB and have not experienced any problem.

My server configuration says: upload_max_filesize 200M

That should not be the problem. I set the upload field settings to somewhat around 190 MB (199480 KB i think). I use the latest Cobalt (error exists from day 1 of using cobalt) and latest upload field.

Okay, I fixed and replicated the error. The problem is the setting of the upload field:

Format Parameters >>> Download link open >>> Open file in browser (works, file is downloaded correctly!)

Format Parameters >>> Download link open >>> Force download windows despite file extension (no error but file is only 1 KB).

That's the problem. Unfortunately I need the setting. Hope this helps fixing it :)

Can you see content of that 1k file? There have to be an error.

The simple notice may brake everything down. Tryt o switch error reporting to none just to test.

Sven,

I can download files around 50 MB with the forced download setting.

:S

I opened one failed download with an editor and it contained this:

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 32921601 bytes) in /www/htdocs/w00f6992/components/com_cobalt/controllers/files.php on line 227

Problem of my webserver?

Sven,

increase the "memory_limit" setting in your php.ini

Maybe a value of 128M or even bigger should solve the problem.

Right. Because to send the file it reads it first into memory. I'll if I can change it to send by chunks.

Where do I find my php.ini ? May be it is a setting, that only my hoster can change?

Sven,

you can see the path to your php.ini In Joomla backend under SITE --> SYSTEM INFORMATION --> PHP INFORMATION

You will find all parameters listed there.

If you dont have access to this configuration file, you might try to set it directly in the affected script.

Check this advice here ...

Good luck ...

Depends on your hosting provider and environment. i.e. Shared hosting and how PHP is loaded. In certain setups, it is also possible to use your .htaccess file...

Thank you both :) I will try the several ways provided. I am using shared hosting at all-inkl.com with an expensive package. I am wondering why it has such limitations. Or does only the script have very high requirements?

I have added chunk streaming for next update. But to learn how to manage memory good anyway :)

Changing the value in .htaccess file (after getting the approval from my hoster) works fine. Problem does not longer exist.

Line for .htaccess

php_value memory_limit 128M

But if there is time someday it would be great to implement a way that doesn't need that much resources of the webserver.
