I have a problem - when i trying to donwload my app to build it, Phonegap Build reads app as AppWP and this app do nothing (default app).
But my app called as MineWP and works great on Phonegap Dekstop. Help!
What are you uploading to PG Build? I'm guessing you're uploading the project as created from PG Desktop, which is incompatible as-is with PhoneGap Build. You will need instead to place a "config.xml" file inside your "www" directory (adjust file paths as necessary), include your icon/splash assets in the "www" directory as well, and then zip up the contents of your "www" directory and upload this to PGB. Otherwise you'll get incorrect results.
(Side note: never upload platforms/ or plugins/ directories to PGB. You're only asking for trouble if you do.)
