Logout and homepage problem, white screen

[Haluska]

Hello, 

i have problem.

If click on logout, returns to the last page, when Presta was realoaded (F5) (in video is last page white screen), but user stay logged. Sometimes is all OK. 

Sometimes if i click on Add to cart (Koupit), nothing will happen, but after this if i click on logo (homepage), a white screen appears (without errors). After reload page (F5) the page will load normally.

I think, its problem in cookies and maybe in Ajax cart, but i cant find error. 

Presta 1.7.5.2
PHP 7.2.19

Some ideas?

it's possible then that you are getting a mod security error, which will not display on front end.  Please see your hosting error log, if you have problem locating contact your hosting.
