Why is this not working? :(

Re: Problems with long HTML code on WiServer

What troubleshooting steps have you taken?
Do the unmodified example sketches work for you (unmodified except for network specifics)?
Which unmodified example sketches have you tried and which ones work / don't work?
Is your access point on the list of known working (or known not working) access points?

Maybe you could describe the symptoms that you are having?

Hi Greg,

I'm sorry and I should've explained myself better.
Anyway, the example sketch for WiServer works just fine, but the below code doesn't.
I'm guessing is because I'm using the inheritance of print, which is exhausting the RAM. Just wild guess, though.
I'm going to try print_P and see what happens.

Roberto.

I actually played with your code last night, moved everything into PROGMEM and it still would not work (for me). At that time I did not know that WiServer had a print_P function and was doing things the hard way (which is error prone and likely introduced the problem on my end). I did find that your code is too long; that is once I removed some of your data (and therefore your RAM use) it seemed happier.

Yep, print_P made it all work for me (and my set of data is purposefully much larger than your set).

Edit - Check out this thread for more better info.
