Restrictions on PHP for Google Gadgets? Documentation?

[bu...@bitexpress.de]

Hello everybody,

First of all, im new to the Google Sites platform and PHP development :D .

Im writing a Google Gadget in PHP for an Intranet Site. Basically its just a simple pinboard, with a SQL Datastore in the background for the post-its. Ive come kind of far in the development and I was always testing it on my localhost. Works fine.

Now i wanted to give it a try and uploaded it to my Appengine account. The only response i get in the Gadget frame of my site is: 

Error: Server Error

The server encountered an error and could not complete your request.

Please try again in 30 seconds.

I know how to upload and run the Gadgets correctly, so i suppose the problem is the code. Is there a restriction for which parts of PHP are allowed on Google Sites and if so a useful documentation?

Im kinda swimming right now, cause the gadget runs fine locally, but i have absolutely no clue whats the problem online (regarding the error message).

Would be great if someone responds me :)

Regards,

Andreas Buck
