Error uploading 10MB+ files server returned: HTTP 500

Hi yodare,

I'm assuming that you have the Maximum upload size in your upload field set to a large enough value or unchecked for unlimited size?

Is it possible that your host has a max ceiling for uploads that you can not override with php.ini?

Hi yodare,

It could be a memory limit that is being imposed by the OS. What does the bottom line labeled "Server Resource Limits " say under: Admin > General

If that's not it you can submit a 2nd level support ticket and we'll take a look. Here's a link:

Hope that helps!

For the actual upload field config, I tried both unlimited (box unchecked) and a value of 51200.
Within Admin > General Settings the last line displays the following...
Server Resource Limits: CPU Time: 120 seconds, Memory Limit: 200 MB, Processes: 64306

Is there any chance CMSB is calling PHP Version 5.3 during the upload process instead of my Default PHP Version 5.2? Other than that, the only possible explanation could be Apache settings trumping PHP.INI during execution. Could this happen even when PHPINFO displays my revised/desired values?

Just a thought in case the server allows the larger uploads and there's no errors being caught...are you, by chance, testing this with just one file or a variety? If it's just one, is it possible the file is not truly a .jpg file? Maybe open it up in Photoshop or Paint Shop Pro and resave it as a jpeg...and if in Photoshop ensure the "web friendly" jpeg is chosen.

Thanks for test file Dave. I put it in the CMSB directory and tested it with a 5MB file and a 14MB file. The 5MB file displayed successful upload results. The 14MB file displayed a 500 Error page.

I called the web host tech support and they mentioned PHP had a 32MB limit (which is BS). The tech support guy put me on hold... 5 min later he said I now have a 32MB limit. HOWEVER... before I hung up the phone, I refreshed my phpinfo test page and it served me an ERROR PAGE! In fact, all php pages within the CMSB directory served up the same ERROR. He stuttered for awhile after I informed him of the directory error, then he said... a ticket was created and sent up a few tiers. [crazy]

Well... I looked into the new issue and it appears the Default PHP Version was changed to v5.3 by Tech Support. I set the Default PHP Version back to 5.2 and my php pages started loading again. v5.3 could have conflicted with directive php.ini values in CMSB directory. Anyway... I'm still waiting to hear back from a more knowledgeable hosting tech support rep. I'll let you know what I discover.

That's a good point equinox69, but unfortunately, it was one of the first things I tried. File dimensions, color-space, unknown extensions, and file corruption can always have the potential for generating upload errors. I tested a handful of different files/file-types; all which produced the same error.

Ok sounds, good.

If they cause problems, you can remove the .htaccess and php.ini in the /cmsAdmin/ folder. They're just there to try and "normalize" the php environment and aren't supported by all servers anyways.

What we've found, is that sometimes it's best to just present the problem to the host and see if they can fix it. You might point them to the demo upload script and ask if it's possible to upload files larger than 10 megs on their server via PHP. The test script doesn't contain any program code at all, so if it doesn't work, it's a clear indication the server has limits or issues.

Let me know how it goes.
