GD Image Library, Thumbnail Generation Alert

I’m getting this error on one of my sites. Similar error as reported here, and here but those are almost a year old.

I “run tests” and get this error. Thumbnail generation test failed!object(WP_Error)#2276 (2) { [“errors”]=> array(1) { [“invalid_image”]=> array(1) { [0]=> string(21) “File is not an image.” } } [“error_data”]=> array(1) { [“invalid_image”]=> string(83) “https://sweetcheeksbaking.com/wp-content/plugins/foogallery/assets/test_thumb_1.jpg” } } array(2) { [“ext”]=> string(3) “jpg” [“type”]=> string(10) “image/jpeg” }

I’m running on Avada theme. My server (a dedicated box on A2 hosting) indeed has the extension running*. Tech support says all looks good on their end – which makes sense.

I’ve tried disabling all plugins except Foo. I’ve tried disabling theme to default. Still same error.

*The thing is, I’m running Foo Gallery w/ Avada theme on this very server on at least 6 other sites (maybe more??) It’s my default / go-to plugin that I use for image galleries (and I recommend it all the time)

Also, everything was working great until something in the last month or so (I don’t recall exactly when the issue came up, but it’s been in the last 6-8 weeks. This site worked great until now, and now, the thumbnails are indeed getting all jacked up and not displaying properly.

There’s just something goofy with this one site. I’ve followed the other 2 posts but nothing there sheds light on my side.

I’ve exhausted all options. Thoughts?
