Cant login after install themes

[mastersly]

Hello When i install mybb and add theme from here its work fine but when i try to login i got this error

Authorization code mismatch. Are you accessing this function correctly? Please go back and try again.

Lets see how to fix it

[hide=9]
GO

admin control panel >> template & style >> tempaltes >> your templates >> portal templates>>member_login

</form>

like this

<input name="my_post_key" type="hidden" value="{$mybb->post_code}"> 
</form>

you also do that step in

portal_welcome_guesttext
 error_nopermission 
 header_welcomeblock_guest

[/hide]

It seems that if there is a problem that is relating to log in after there is a change with the theme that there is likely a change that was made to the code that is offsetting the log in.

Well, this has not happened to me and I have never tried to find a solution for this. However, when I have login issue on wordpress site, I access my site through cpanel and change passwords.
