I searched the board for two days trying to find someone who had a similar problem, but I couldn't find anything interesting. Here's the issue: I have pictures which have a very big resolution, sort of like 5000 x 5000 pixel. I do know that usually it's better to resize them, but I don't want to. So I used to use the typical method with admin tools. First I upload the resized pictures and add them. Then I upload the original pictures replacing the older ones and I run the admin tool to update them (thumbs only).
HOWEVER now when I run the admin tool it gives me a blank page. I tried limiting the pictures to 1, unchecking the auto-refresh option... still nothing. I checked the error log, nothing. I enabled debug info... nothing again. Just a blank page.
Any idea on how to solve this?
