Question Error 500 Uploading Multiple Large Images

Hi guys, I've been trying to diagnose this problem for a while now. If a user uploads multiple large files (Eg. original sized digital camera shots), Kunena will upload/resize/post the FIRST one, but generate Error 500 and not return to the post.

You can upload multiple images just fine if they've been resized to smaller than the forums size limit (3000Kb file size, 1024x768).

Here's the diagnostics report:

I dont think this is specifically a Kunena issue but possibly something in my server/PHP config. Any suggestions ?

Thank you for your question. I don't have a specific answer but you may be on the right track as far as PHP being involved and the 8 Mb total file upload that you have in place on your website.

Although Kunena can handle image uploads, people often forget that Kunena is a web-based, text-oriented discussion forum product. In other words, Kunena's main utility is to allow people to discuss things. Images are important but they much better products that are available that allow people to share their images, catalogued and organised in ways that make them easier for others to access them and with improved security mechanisms to ensure that only those people who should view your images can view those images. Kunena doesn't really do those things as well as a lot of other products do.

So, if you're having problems uploading or distributing large-sized images, you might consider alternative software to handle these needs ... at least as a workaround.

Hi,

Just increase you max file upload. It's right now set to 8MB. So anything more than that will cause your apache server to abort. This is outside the control of Kunena. Try setting it to 32 or even 64MB if you want to allow multiple large files to be attached at once.

Hope this helps!

I'll try this today and let you guys know if it worked or not

I think this is related to the server itself, there's a 90 seconds time out occuring somewhere.
I'm using GoDaddy's Windows hosting (IIS7 & PHP5.x), but suspect the issue lays within the hostings IIS7 settings.

I think its just the size of the files is effecting it due to the upload times.
