Our gallery seems to be selective in what recent photos it's exhibiting. Seems like a recent problem (pun intended), where all new uploads are not automatically shown (when they had been in the past). Seems only a few are being shown, not sure why the selection process. I have not made any admin changes to our gallery so haven't tinkered with the setting. Any suggestions?
Caching was set to 10 minutes. I did as you suggested and it seems to have fixed the problem and all recent uploads are now showing. Really weird though since it never had that problem before.
