Lower digital resolution link upon purchase doesn't work

[jpbgibbons]

Hi, I am nearly complete with my WP photo seller site, and have been testing it all by buying my own photos online (at test prices!). All is good except the digital half size photos (ratio 0.5). When I amend it to 1 it works fine, but back to 0.5 and the purchase link results in a Server Error 500 webpage when I click on it. I tried .5 and same thing. I read the forum and amended the Permalinks settings for the Word press site to select “post name” under common settings, but that hasn’t made any difference.

IMG_9828 copy – Digital : Half Size(1872×2808): [http://shop.skyworkswa.com/?wps_file_dl=1&id=4&duid=62471ae20dc54b718b874c6337b9426f]

Hope you can please help ASAP, Thanks

What happens when you try another ratio – eg, 0.75? Same behaviour?

I just tried a few tests on my test server and all works fine, so this must be something on your server.

Please check your server error log file to see if any logs are being generated related to this issue.

Also enable debug for photo seller: go to settings page and scroll to bottom.

Hi, I’ve enabled the debug as you suggested. I also tried 0.75 – same thing.

I’ve checked my server error log and there are no errors logged at all.

I spoke with GoDaddy and they said that the problem appears to be that the link being generated by the WP Photo Seller plugin is not a valid link, hence the Server Error 500

Can you please advise further?

GoDaddy…said ….the link being generated by the WP Photo Seller plugin is not a valid link

I don’t know how they came to that conclusion, but I am confident that the URL is correct. It is the same general format as the one for the case where the download works for the fullsized image.

I think the issue is either your server or maybe something else conflicting with the resizing process. (NOTE: the plugin has to resize the full-sized image when you choose one of the smaller sizes. This requires memory and processing power so maybe your server just can’t handle it).

Are you on a shared server?

Can you please do the following plugin/theme conflict tests:

Am struggling here. I changed the theme to a WordPress version available (Twenty Fifteen) out of the few available – there didn’t seem to be any WordPress Default one as such.

This didn’t make any difference – the link still didn’t work.

I then looked through the other plugins – there are only a few installed, and couldn’t see that any of those had known conflicting issues.

I have installed the “Theme Check” plugin, but have no idea how to actually run it and see if it comes up with any conflicting themes!?

I have given up with the lower resolution option and am now just offering full size images only.

Try the following simple test:

Open the settings page for one your galleries (or create a new gallery) and upload a small photo (say no bigger than 800×600).

Then try a test purchase of this photo and buy the 0.5 size and try to download it. Let us know what result you see.

Hi, yes I did that with a small photo and the link worked for both full size and half size. Now how do I do the same with large photos, because I need to be able to sell high quality full sized images (around 6MB files)?

[Peter]

To achieve what you want to do you need a server which can handle the job.

The processing of high resolution photos requires php memory and more grunt than what you have.

One analogy is that you want to achieve super-car performance using a little 4 cylinder Hyundai.

It’s not just the photo seller but any photo processing tasks which involve operations such as resizing your large 6M images will fail on your current server because you don’t have the memory.

You could try asking godaddy to increase your php memory_limit to 256M, but even though the php.ini file might say you have that much, I think for shared servers such as yours you might still be limited to what the server allows.

I personally recommend that you get a VPS plan at the very least.
