Watermark suddenly stopped working

Hi,

I’m using Scissors and Watermark 3.2.1 on a WP 3.5.1 version single site installation with Suffusion theme.

The plugin worked fine for me for 2 days, with or w/o the auto-watermarking uploaded full-size image. The watermark image is “https://www.yuhua.org/wp-content/uploads/watermark.png” and plugin path set as “wp-content/uploads/watermark.png”.

Several days ago when editing one new post, it suddenly stop working from the 2nd image. Tried with manual watermarking, reset and retry, remove plugin and re-install but all no luck.

I checked in image folder, every time manually apply watermark, all image files’ modified date are changed to current. But doesn’t like before, now there is no timestamped “-rect.jpg” file generated, and no data insert in postmeta table. Besides no php error logged.

I’m not sure if this is related to “DB Cached Reloaded Fix” and “QuickCache” I installed. But I did deactive and remove the plugins but still no effect.

Can anyone help me? Thanks!
