Some help needed with emerald theme

[letsearn]

Hi,

We have just installed the Emerald theme to our forum and after installing the theme the plugins which we had are not working Plugin 1- Thank You/Like System (3.2.0), Plugin 2- My Advertisements (2.3.2) 

And also some images are showing no image logo screenshot : http://prntscr.com/mvupm6 | http://prntscr.com/mvupwp

Also wanted to know how we can allow users to add the images/avatar so it doesn't look like this in their profile: http://prntscr.com/mvuqt6

Thank you

Also forgot that how we can remove the white part from the footer http://prntscr.com/mvv0ic

After changing to Emerald i just noticed that now i am not able to login to my own website? it gives this warning no matter if i register new account or login (Authorization code mismatch. Are you accessing this function correctly? Please go back and try again.)

Please install the plugins AFTER you install the theme, because the plugins make edits on the templates.
