Ok, only disabling SG optimizer plugin it perfectly works.

But, now, the question is.. how I can I add the exclusion css class like Ruzard replied? 

Thanks very much and sorry for the patient.

Hi, 

I don't know if my issue is the same of elliebc, but I don't see the images in home and category when I select  "General Options > Homepage Layout > Grid Posts " and  "General Options > Category, Tag, Search, Archive Layout > Grid Posts ".

I attached a screenshot. 

I have followed your reply checking in the plugins page, but I don't have other plugins that support lazy load installed.

So... could you help me, please?

Thank you very much.

Might be useful for SiteGround hosting users:
They install SG optimizer plugin. They don't allow to switch off lazy loading of images only. However possible solution is adding an exclusion css class to their list. "penci-lazy" in case of soledad theme will work like a charm.

hi there, since Sunday my thumbnail and featured category images are not loading at all on the homepage and other landing pages and blog grids. I've just updated to the latest version of Soledad, but the issue is still happening.
