Hello Rami M'Rad,

Thank you for choosing our theme.

1) Please go to each portfolio single back-end and scroll down to Elated Portfolio section and delete all from the Portfolio External Link field

2) For that certain Portfolio list type use can change overlay color using some Custom Css code, just paste it into Elated Options > GEneral > Custom Css field 

.eltdf-portfolio-list-holder.eltdf-pl-standard-shader article .eltdf-pli-image:after{
    background-color: red;
}

3) What exact pattern you are trying to remove, can yo u please be more precise preferably followed with some screenshot. However, if you are referring to this image 

go to back-end of each page that has such separator, open each Elated Section Title's settings and there choose No under Enable Separator 

Please let us know if this solved the issues and if there is anything else we can do for you.

Thanks.

Hello there,

That pattern image is actually background image appended to row, it can be removed using some Custom Css, and the best way to do so it to add each row that you want to remove that background image class by opening it's settings 

and setting it's class to be, for instance row-no-image, and than just add following Custom Css code into Elated Options > General > Custom Css field 

.row-no-image{
    background-image: none!important;
}

Please let us know if this solved the issue and if there is anything else we can do for you, or you need more help regarding this issue.

Hello,

Another solution is to obtain the row that has such background image, than just go to back-end find that row inside Visual Composer, open it's settings and switch to Design tab and there click x for current image

Please let us know if this solved the issue and sorry for the previous answer that didn't solve the issue.

Thanks.
