I did all this, I have Elementor Pro and a backup plugin, but I don’t think that could be it. After all, they are necessary. And on the login screen I didn’t make any changes, just inserting some snippets that I saw on your github page.
Honestly, I don’t know what else to do, The customers complain that when they enter their login details, the screen is requested again.
Sometimes it works and sometimes the login screen repeats, but when switching menus and navigating, it is clear that the user is logged in, but for lay users, they will think that the login did not work because the screen is displayed in a loop
We checked this issue from our side, and it seems okay. The above factors can cause this issue, and yes, Elementor can also cause this issue. Also, there may be relevant restrictions on the part of hosting providers, so I recommend checking this in more detail.
