Hello!
I set up the new wordpress 4.3, on my private server. I went through the steps and the installation has no errors. I made my own theme and installed it. When i tried to load the header for my page, it logged me out. (also i could not upload the header .png 100 Kb large)…

I’m confused, cuz wordpress is not acting like it should, after the first time it logged me out, the logging out started to occur randomly.

This is not the first time im using wordpress and i don’t know what the hell is going on…

Please direct me to the answers cuz i’m losing my mind over this problem. Should i delete the whole wordpress installation and start from scratch??
