eStore "Cannot use output buffering in output buffering display" S3 files

[DeepLiving]

Hi, i’m using WordPress 4.1 and WP eStore 7.1.7.

I have zip files on Amazon S3, and have been using them for years via eStore. Suddenly, when customers (or I) download one of these zip files, only a small file is download, containing error

<b>Fatal error</b>: Unknown: Cannot use output buffering in output buffering display handlers in <b>Unknown</b> on line <b>0</b>

When I take the unencrypted url in WP eStore and paste that into a browser, the files download correctly.

Please help?

Thanks

Bennie

It sounds like you have not properly followed the eStore to Amazon S3 integration instructions:

When properly integrated, all downloading activity is handed off to Amazon’s servers.

Thanks wzp, it may very well sound like that.

I’ve been using it (WPEstore/S3) for a few years now and have sold a number of those products all ok – and then suddenly it stopped working.

I will go through the instructions again, and maybe it won’t kill you to be a bit more helpful either?

I’ve been through all the instructions again, and done more testing; 2 hours of it, so I’d really appreciate if you could help me troubleshoot this rather than just telling me to read the manual again, thanks. (not being sarcastic, I’m seriously asking for help as I cannot figure out where I’m going wrong, thx).

In my testing I have moved multiple files, some non-zip files, some zip and some large (e.g. 188mb) zip files, to the same Amazon S3 directory.

I then created a test product, with 3 digital downloads, with the the exact same url (I use a CNAME),but of course with three different file names.

The non-zip and small zip file downloads perfectly, but the large zip file still only downloads a small file with the error message

<b>Fatal error</b>: Unknown: Cannot use output buffering in output buffering display handlers in <b>Unknown</b> on line <b>0</b>

Any suggestions on what else I can try, much appreciated.

Thanks

Please enable eStore debug logs, save the settings, and then reset the logs. Use the Admin Functions to manually generate a link. Then try the link. If an error occurs, please post the UNEDITED & UNREDACTED contents of the Download_Manager_Debug.log file.

Anyway, I played with the url and got it to work as

as3tp://s3.CHAME/folder/folder/file.zip

It never hurts to keep “going over the instructions again…”

I couldn’t agree with you more.

It’s just that your instructions in the video and https://www.tipsandtricks-hq.com/ecommerce/amazon-web-services-simple-storage-service-aws-s3-integration-1101 does not work for CNAME setups.

I think you’re the second person in 3 years that wanted to use CNAME aliases:
