When I used Theme-Check plugin to check my theme, it gave me many warnings of base64_encode() like following:
WARNING: Found base64_encode in the file [file name]. base64_encode()
is not allowed.
And almost file names listed there are from OptionTree plugin that I used for creating the theme options and meta boxes. I also used base64_encode() for my purpose at some parts.
So, I'm not sure what to do to resolve these warnings about base64_encode(). Could you give me any advice?
