Thank you for your prompt reply.
The client requires the site to be the same on pc and mobile since mobile supports only single/two column display which rearranges the design of the page.
I am using go daddy techtra theme which supports responsiveness and I have disabled that through the theme settings.
I couldnt find the file pb.php located at (wp-content\plugins\ig-pagebuilder\core\pb.php) but I found the code you mentioned above in (wp-content\plugins\ig-pagebuilder\core\core.php)
I tried both commenting and removing that code but it didnt affect anything. Columns are still re arranged.
Any further help would be much appreciated.
