[Stijepo]

Hi,

i have an issue with error showing on homepage when not logged in. Actually it shows:

That action could not be completed. Please try again, and if this occurs again please contact the system administrator and tell them how you got this message.

When i go to debug it shows:

If i login and after that i logout i can see front page of the forum with modules and channels.

I am trying to locate what could be the problem but cannot find out so far. If someone can help...

I have another issue if i can write here... On my Android phone when i try to login on my forum it only refreshes but nothing happens. I have tried original vbulletin theme and my paid custom,none of them works. What can be the issue for that?

A couple of reasons are:

1) Your device isn't accepting cookies for your site. They could be turned off in the browser or you can have some addin that is blocking them.

2) You're not accessing the site from the URL specifically listed in the AdminCP under Settings -> Options -> Site Name / URL / Contact Details.
