I have just checked foe you and my end shows a menu option titled “Clients Only portal”, which doesn’t match either of the options you suggested above.
I know you have mentioned caching, but have you tried viewing across different browsers/clearing browser cache etc.?
Also, if you use cloudflare, it pays to go into the caching settings and turn on development mode, as this stops any caching whatsoever.
It can be super frustrating, but it’s most likely one of those things that just takes a little while to tick over.
There is a ‘Client Portal’ menu in your blog pages.
It seems you have multiple menus.
The menus in home page have class thrv_*** or tve-***.
Isn’t it something to do with Thrive Visual Editor Plugins?
Pls check the plugin setting or widget.
