shader error when compiling for web player

I’m getting a shader error when trying to compile a project for the web player. The project was originally an ios project.

Shader error in ‘Hidden/NFAA’: Program ‘frag’, error X4506: ps_4_0_level_9_1 input limit (8) exceeded, shader uses 9 inputs.

the error is in Image Effects (Pro Only) in Standard Assets

What do I need to change to get it to build for webplayer?

Try forcing a higher feature level.

#pragma target 3.0

I had the same problem, it was one of the quality settings Antialiasing at 8x, put the higher quality setting in 4x and the error was gone
