Hi
The compiled CSS (/templates/rt_protean/custom/css-compiled/protean-joomla_18.css?5955c3df) is overriding the colors of other Bootstrap button classes such as .btn-success and .btn-info because it includes the style rule for:
p.readmore .btn, .content_vote .btn, .contact .form-actions .btn, .login .btn, .logout .btn, .registration .btn, .profile-edit .btn, .remind .btn, .reset .btn, .profile .btn, .search #searchForm .btn, .finder #finder-search .btn, .edit.item-page .btn-toolbar .btn, .pager.pagenav a, .moduletable #login-form .control-group .btn, #searchForm .btn, #finder-search .btn, .btn
As you can see, the last rule of that list is .btn, which overrides all other Bootstrap classes. Where can I remove the .btn declaration? Also, it seems weird that .btn is used instead of .btn-primary, and I feel it's generally not a good idea to override output of Bootstrap classes as other 3rd party extensions use them too.
