Hello, I just purchased WP Smush Pro again today. For a little while, my credit card number was changed and the renewal couldn't renew so it (presumably) rerouted back to free version. I didn't realize it was not renewed and yesterday I attempted to smush the images and after waiting for the process to complete with no errors, a gtmetrix scan still indicates my images are not scaled and optimized (which it did not say this before I recently posted 2 posts with their featured images now displaying in my blog) I then clicked re-check images and it then displayed the same number of images needing optimization as before I ran the smushing process. I noticed this same occurrence even after I re-purchased the WP Smush Pro, except it actually read-out about 6 images that were skipped, I suspected that meant it was working but to no avail. I suspect that the plugin did nothing at all but said it was processing the entire time. I would greatly appreciate any assistance with this issue. Thank you very much and have a marvelous day!
