Invalid security token

[samkanx1]

I have copied on a free (ftp and cpanel only, no ssh) account my Grav install from localhost. Everything works, I can login Grav as Admin or normal user. But when logging on Grav Adminpanel, I get Grav notification - Invalid security token. It does not stop me logging in. Have done everything I can from Grav manuals. Nothing helps.

Also, probably related issue - when adding a new picture on any Grav page, it appears ontop of the page unasked, whithout a link on the page to it. Seems to me it could be related, as old pictures, added while still on localhost do not show up unasked.

I suppose there is something specific I have to do either with Apache configuration or something.

Where do I have to look for a possible clue?

Thanks, yes, have tried everything in there, except the parts, which require ssh access. Still no luck.
