3.19 still not working (loading forever)

Hi, I see you closed as resolved previous opened issues, that heven’t been never resolved.

The gallery is loading forever on my site, please check: vinodivino.spb.ru but if I create a dedicated page it works (look at the footer, it still not working).

if I edit the footer from WordPress it works, ubelievable. It’s enough to have the edit menu column on the left to see it working.
I can tell you that when I’ve tried today the token was expired.. but on main page the plugin still loading forever (while on the test page it displayed the error), that means the main page still even not connecting to Instagram.. the error is somehow before, I really hope you can solve it.
You asked me to disable all other components to see if it back working, but if I do it my site will not work again after renable.. strange but it is that. Anyway if you need that I can backup all and restore, eventually.

There is no other way to find the problem inside log files? Where the log file is stored? How to activate eventually a debug? Thank you
