The maxshowndata setting is a runtime parameter, not a blockchain parameter:

And gettxoutdata is an API command:

Hey Team

we are still struggling,

as per the new blockchain parameters we are set upto 19MB file, but as we try to upload 2 or 4 mb file, it generates the hash,

as we try to open up the hash transactions it gives server error " A server error occurred.  Please contact the administrator."

please have a look at

Hi Team,

it has progress a bit,

http://34.221.164.11/multichain-web-demo
http://34.221.164.11:2750

we are able to publish larger files using web demo interface, but the same is not working at POE,
we have increased the size of upload & post size value at blockchain hosting and client hosting, blockchain parameters are all set,

but as we attempt from POE, it stops working...can you guide on what is happening.

Can you please explain what is this "POE"? Do you have a way to view the responses from the MultiChain API at the POE? If so what do you see when attempting to upload data from there?
