Serious log in issues

I have really serious issues with my log in. I keep getting logged out from this website (no problems with other websites). I’m trying to upload my first WIP project, but it already took me 4 hours without succes. I have uploaded images to another website because when i try to upload them here, i got logged out again or it tells me i dont have permission.

The problem is that the website logs me out every page i visit. Hopefully anyone can help me fixing this?

(third time trying to post this thread as it logs me out when posting)

Did you enable ‘Remember Me’ when you logged in

Yes, i did, i also checked my cookie settings for Chrome…everything should be ok. Have to say, I haven’t been logged out for some mintues now…
