Subdomains reverting back to main domain on sub domain logout

I have a multi site domain setup everything works well but when you log out of the sub domain it reverts back to main domain.

I have tried the fix … https://www.ads-software.com/support/topic/wordpress-multisite-sub-sites-all-redirect-to-the-main-site …

“In the table wp_X_options (where X is that site’s ID number), under the option_name column (field) find the active_plugins row.
Change the option_value field to: a:0:{} ”

it did not work I am running 3.51

Is there any other conifgs that can be made ad if you allowed others to create subs on your network you surley wouldnt want each log out to revert back to main site domain.

the main domain is https://www.taskbargains.com and the subdomain is https://www.freelancerwizard.com

Thanks
