Rikard – to inform you – I was able to fix the problem by choosing “no gap” in the masonry gallery settings (Gap between elements). When its set to 1px then problem persists. Without the Gap – there is no problem :)
Hey Victoria! Thanks for the help – it solved the issue. I added that to fix the white line problem in the gallery, but it didn’t work so forgot to remove.
Can you please comment on the second questions: Is it possible to add picture (logo) where the title is supposed to be? So instead of text – there is a .png picture. If the title would support html – then I assume it wouldnt be the problem, but in this case, it seems not possible.
