Hi part of the problem was solved but the last two questions not. The changes are concerning the portfolio page.
(http://convitando.com.br/galeria/)

1- I still don´t get a perfect grid in this page (you can see that I have a problem in the second and the fifth lines.)
2 – For exeample if you apply the filter called “convites” it will show only 18 itens besides having space for 20. Why this happens?

Thanks again

No
I use the child theme and the olnly thing I’ve changed is styling in the styling panel.

Thanks

Thanks
