[SOLVED] help needed with center column product page edit

[Dromihetes]

Hello,
Can somebody help me with the file name, where I can edit the margin top of the center column in the product page?
I would like to bring the columns to the same height

 

like this:

 

but the only location indicated to me, is a cache file...I looked in global.css, product.css, and other files, but with no luck.
The code line that needs to be modified is:
pb-center-column {

margin-top: -15px;

}
and I need to have margin top 0px, in order to have the columns allined.

We are using Warehouse Theme, and PrestaShop 1.6.1.24, if it matters.

Thank you!

Hello, the right place for product page is product.css. Turn off css cache.

And some themes can use and edit own css files and cache them. So you can try to search them in the folder of your theme. Also, you can try to search the settings for them in settings of your theme.

Hello,
Thank you, for your reply. 
I've checked the file product.css from the theme file, but there is no mention of the center column top margin padding, but I can find it only inside the cache files.

I looked also in the global.css from the theme file, but again, with no success...if you have any other recommendations, I am all ears.

Hello Webprog,
Your solution about turning off the css cache, worked. It showed me the location of the margin top, located in the public_html/modules/themeeditor/css

So, thank you, for your help!
