I have issues creating thumbnails and I got some new findings when checking
the images/thumb/ folder and the Special:ListFiles page.
I found that:
Before 24 May 2016, all thumbnails can be correctly created. Every image I
uploaded had 120px, 180px, 320px, 500px, ..., 2000px thumbnails stored in
/images/thumb.
On 25 May, only 120px thumbnails can be created and stored.
After 28 July, no thumbnails were created.
(I did no uploading between 25 May and 28 July.)
Is there any thumb/ folder storage limitation? What may cause this strange
problem?
Thanks,
Jingyi
