All right, theme author gave me a compromise; put the sidebar black so we can, at least, see the widget. he gave me this to copy paste in Theme Setting > Script > Custom CSS

#page_content_wrapper .inner .sidebar_wrapper
{
background: #000;
padding: 20px;
box-sizing: border-box;
}

It helps a lot.
I ask him anyway if there was a chance that they could make a change in the script to prevent theme from enabling thumbnail of event as a background image. I know this request can be a lot, lot of work and theme author might refuse to play in the script for this glitch with the plugin (I understand!), also, it’s not like a lot of people reported this problem, but I ask anyway…it could be as simple as a line or two of code added, you never know.

Found this in Edit Theme:

Sirius: Page with Sidebar Page Template (page_r.php)

read the code, and found this:

//Get Page background style
if(has_post_thumbnail($current_page_id, 'original'))
{
    $image_id = get_post_thumbnail_id($current_page_id);
    $image_thumb = wp_get_attachment_image_src($image_id, 'original', true);
    $pp_page_bg = $image_thumb[0];

I am very afraid to touch that cause it’s the script and I don’t know the first thing about that but…?

Thanks a lot caimin; I just ask your question on the comment page of Sirius; waiting to see their reply! Will keep you post.

If only I was better at this! I’m checking with theme support but they throwing the ball saying they do not support third party. damn.

If this can help: I tested a bright color in the Boxed Background Color of Theme Setting Sirius and this is where the problem is; somehow, the Event image bypass the Boxed BG Color…
I wrote to Sirius support but I’m having second thought about the Theme being the cause…

Hi caimin and thanks for the idea ??

I checked Theme Setting, Background and everything is empty by default; Content BG settings are set to black; BG image slots are all empty; I tried to put an image in the slots to verify but nothing hapen on the event single page.

Still searching!
I will write to the theme support, see if they can help and I’ll follow through with you guys. Thanks
