When I log in with SCLogin module the Top menu item is hidden

What mode are you using the SCLogin module in.. normal or modal? The only recommendation I'd have is to set the "Include jQuery / Bootstrap" setting in the SCLogin module to see if that helps.

If not, please let us know a page where we can see the issue and we'll gladly try to help and investigate.

Thanks,

If it only happens with Super Admins, my guess is that the issue isn't related to the SCLogin module specifically. Can you try enabling the standard Joomla mod_login module and authenticating with that to see if the issue persists? If so, that would confirm the issue is not caused by SCLogin.

I'm not sure then. Without being able to see the actual issue, it's very hard to determine the problem. When you enabled the standard mod_login module, was the SCLogin module still enabled on the page, or was it disabled? If disabled, try leaving it enabled on the page to see if the problem persists while using only the mod_login module to authenticate.

That may help narrow things down some. Beyond that though, I'd suggest trying with any different user groups you have configured on your site to see if it's just Super Admins. If so, try to determine what may be different for Super Admins. If other groups are affected, that may help narrow things down too. Either way, if it's possible to send some credentials for us to test, it should be easy to narrow things down quickly. Without them, we don't have a lot of information to diagnose further though.

Thanks,
