I looked around a bit, but couldn't find it.
Specifically looking for 'Show Sidebar' option in UCP > Edit Options > Other Options. I'm guessing that was injected by Advanced Sidebar.
User Control Panel Templates >> usercp_options
if you are referring to Advanced Sideboxes plugin then it does not directly edit usercp_options template
I'm looking in usercp_options template, but see everything BUT the lines of code regarding 'show sidebox'. But it shows in front end User CP>Edit>Other
Here you see 'Other options' begins with 'Show friendly redirect'

^ what exactly you want to do with the side boxes option shown on user control panel options ?
./inc/plugins/asb/forum.php file has related code (at the bottom)
I want to remove it from user options so they can't turn off the sidebar. Thanks for the location. I see it line 210 in /asb/forum.php . Amazing how it can inject itself to show in front end without any mod to the usercp options template.
^ you can simply comment out below code by using
// at the beginning of the line so that the sidebox option is not shown at user panel
$templates->cache['usercp_options'] = str_replace($find, $usercp_option, $templates->cache['usercp_options']);
Just to tie this all together, we have discovered
here that removing that line will result in user's losing side boxes if they save any other options.
This will be made an admin controllable option soon so such workarounds are unnecessary.
