It appears the gallery refers to
Code: Select all
/media/com_phocagallery/images/phoca_thumb_s_no_image.pngfor some (random) pictures.
The problem has occured before in alpha, but it has not been solved.
By cache settings I assume you refer to Joomla Global Configuration settings (System settings). In those settings caching is disabled for my site.
Post edit:
It seems the problem is related to the "Category View" setting of "Different thumbnail height". I had it set to "Yes (Masonry Effect)", and when I change it to "No" thumbnails load and show normally. I tested changing the setting to "Yes", and that also causes problems, which are a bit different. So, by changing the setting of different thumbnail size to "No" all thumbnails are shown ok. Perhaps Masonry Effect requires some additional work?
