I have a wordpress page working fine in my LAMPP local server with Php7.2. Everything is going fine. Now I have it in Strato hosting server. I can see main pages, but when I go to the admin side, I only can see the login form, but never go into. I've enabled debug in Wordpress and server logs show me
"End of script output before headers: index.php"
I'm using the same version of Wordpress (5.1.24) and Php (7.2) with my own theme.
After 10 days I've got my problem solved. The problem was caused by Ultimate VC Addons and newer version of Wordpress. Once I paid for new version the problem was solved. The obsolete methods dissapeared.
