thank you for making deleting my whole website

Sound like you need to clear the web browser and webserver cache to see the results. I am testing this plugins as well and at first i experienced the same as you did but finally figured it out the cache issue.

No man , i have tried from different clients such as: VPS, work computer, personal computer, sister’s computer and was the same thing. and a short mention: i did not used any cached plugin such as supercache or totalcache , anyway i managed to fix it reinstalling wp and avoiding using this plugin.

Sounds like your watermarked the full size image. This was your problem. The settings in the plugin warns you about doing this. Simply because adding the watermark to the full size image makes it where there is no image on your site without the watermark. So when you regenerate all your images even with the plugin turned off it does this from the original image which has the watermark on it.

Nope, DoodleDogCody.
I didn’t applied the full-size watermark setting.
I also regenerated, deleted, uploaded the images and deleting anything releated to plugin from folder, database, etc and still appeared.
So, anyway my first post was a little bit raged.
i will never use this plugin and that’s it , the problem is solved.
