ClassiPress 3.1.9 LOGIN problem, can't post ads
so I just installed ClassiPress on my website and started to setup the theme when suddently I noticed that I can no longer post ads. When I log in from the website, either with "admin" or another username/password, it redirects me to the login page again and on the top it's written "welcome, [whatever username]". But then if I click "Post an ad" it gets me back to the login page, just like if I didn't login. Same thing if I click on "my dashboard".
I am able to log in the /wp
-admin/ with my admin account and go to the Wordpress dashboard, but if I go back to the website itself I have the same problems.
Anyone have an idea of what's going on ?
I tried to deactivate all the plugins (I just had time to install one lol). I tried to deactivate and reactivate the whole theme also...
It's a bit frustrating because I just bought the theme and I was only getting started..
--> feel free to create account, or try with username:user02 / password:123456
Thanks for your help !
