I have an issue with the main blog page with the list of blog posts. When I want to set up the blog posts list to Masonry mode, it is completely misaligned. I have tried to purge the cache several times, but with no effect. It is perfectly ok with the 3 columns mode.
Can you please turn on the Masonry setting on russiemeconnue.fr so I could have a look at your issue live (I can not track it down by the screenshot). Please let me know when you turn it on, and I will take a look. Thank you.
