Hi mberwing,
I have checked and see the site used the following CSS
.t4-masthead .ja-masthead:before {
background-color: #321573;
opacity: 0.95;
}
in the:
/templates/ja_eventcamp/html/com_easyblog/styles/custom.css and /templates/ja_eventcamp/local/css/template.css file:
To resolve this issue, I have added a custom CSS code to the Backend > site template styles > ja_eventcamp > Tools > Custom CSS:
.t4-masthead .ja-masthead:before {
background-color: #1c1e52 !important;
}
You can check your site now.
