Topic: Valid Header...
Tested the free version and am trying to upgrade after purchase. Currently running wp 3.2.1 w/ Weaver II v. 0.7 with version of SimpleViewer Pro I downloaded last night.
I have /uploads folder w/ full permissions. I've tried both standard install process (upload via plug-ins) and when I attempt to Activate, it fails due to no valid header.
I've tried the other by unpacking the zip and placing it in content/plugins/ directly, but then it does not show up in the plugins admin panel.
Thanks for your help...and happy turkey day!!
