You may want to try this on the template_css.css. I am not a coder and have it trial and error to make the width i wanted.
#ja-mainbody #ja-content {
float: right;
width: 70%; /* Modified it to make main body bigger */
padding-right: 2.5%; /* Edit the right padding */
}
Reduce the right column
/* RIGHT COLUMN
——————————————————— */
#ja-rightcol {
float: right;
width: 17%; /*i edit from default 20%*/
margin: 25px 0;
}
I saw your website, how you managed to disable to path way for ijoomla? I also have it install in the front page but have duplicate pathway. Something like home/home/ ?
