Solved Issue with div.pagination colour

Hello,
I was just given access to a website in order to install a forum so with some research I found out how awesome kunena is, but on the flip side I consider myself uber noob when it comes to customisation. So, I am having this issue

As you see the navigation menu is black and I want to make it transparent. I know that it has something to do with the website's template (which is JSN mero) and tried to find how to fix it using Firebug. I've found that it has to do with div.pagination and I need to edit the template.css at the website. The problem is that I don't know the exact code that I have to add at template.css in order to fix it.
I also have an other question regarding the language which instead of Greek I'd like it to be English by default but I guess I need to open a new thread.

Copy the code from Fiebug and add this code in your Kunena custom.less

Example:

You're right, different question should not be discussed in the same topic.
Kunena shows the language which is chosen in Joomla as default.

Well I added this code

div.pagination {
background: none;
margin: -12px 0 20px;
line-height: 1;
text-align: center;
}

at the template.css and it worked like a charm. Thank you though for your responce
