Sorry but I can not give you the credentials, it's not my site.
Hm, if that is the case, that is very difficult for us to know what the issue caused this.
Perhaps you can discuss with your site owner and see whether that is possible to clone this live site to another testing site, so we can investigate from there?
I have another easy question for you..
1 - The height of the box of the post that are in evidence it's not the same.. look the attach.. (blog3.jpg)
There is a small step between one post and another
The reason why we don't put it as 100% width is because different browser has their own different standard, If we put it as 100% width for the 2 columns display part, some of the browser unable to handle it very well, so the second column unable to fit it, then it will display all the post at the left column.
By the way, if you want to show 100%, then you can try download my attached file and replace into your current template override file location
JoomlaFolder/templates/YourCurrentTemplate/html/com_easyblog/blogs/latest/default.main.php , you have to manually create those new folder.
2 - The data are in two lines.. I don't know how to solve (blog4.jpg)
It seems like this issue also conflict with your current template styling.
Can you try apply this following css into your site backend > Easyblog > theme > custom css , it should work fine now.
body #eb time {
width: inherit !important;
}
