Hi @piotreba
I would like to try to understand what is happening with the journal images after the upgrade. The images that were uploaded under “Title image” in Setup 5.1 and 5.3 are not used any more, thus they will not appear. But the images that were uploaded as “Journal Logo” and “Journal Thumbnail” in journal Setup 5.1 and 5.3 should be there after the upgrade as well. Could you please take a look and tell me what journal images did you have in OJS 2.4.x and if they are in the public folder after the migration (they have the following names: homeHeaderTitleImage…, homeHeaderLogoImage…, pageHeaderTitleImage…, pageHeaderLogoImage…, journalThumbnail…)?
Thanks a lot!
