Hi Andy,
Thank you for your answer.
Unfortunately this does not work…
I use these plugins: Block Bad Queries (BBQ), Enhanced Media Library, Local SEO for Yoast SEO, Simple Image Sizes, WP Retina 2x, WP Rocket, WPS Hide Login, and Yoast SEO.
– Perhaps there is an incompatibility does it?
– Or maybe there is a particular configuration does he do?
Thank you.
I solved the issue.
It is a careless mistake.
I changed the image size of the portfolio grid, the options of “Grid portfolio”; by choosing “Set the size of the portfolio grid automatically …”
And everything works perfectly.
Thank you very much! ;)
