Thanks for the additional information. I paid attention on that after read of your 1st message, but thought that text is shown by WordPress/bbPress that way. Please check the double quotes used at the shortcode. Instead of

[user_role_editor roles=”caclient”]

ordinal HTML complied double quote symbol should be there:

[user_role_editor roles="caclient"]

The same problem should be fixed here:

[user_role_editor roles=”affiliate"]
