Thumbnail Generation Alert!

Hi @nin0,

We haven’t heard back from you so will assume that you have fixed this issue and we can mark this support request as resolved.

Thanks for replying. We’ve had no other reports of this issue that I’m aware of so it very much sounds like it may be something to do with your web hosting.

Would you please send an email to [email protected] and include the URL to this support ticket in that email:

I’ll then work directly with you to see if we can identify what is happening and get it resolved for you.

Hi,
I also experienced this same error and I am on Pressable hosting. They said the way the plugin is calling for a specific file is not compatible with their platform. They resolved the error for me by changing a function in wpthumb.php on line 85.

They changes this:

private static function get_home_path() {
return str_replace( str_replace( home_url(), '', site_url() ), '', ABSPATH );
}

To this:

private static function get_home_path() {
return str_replace( 'wp-content', '', WP_CONTENT_DIR);
}

Hope this is helpful.

I was able to resolve my issue by going to settings, images, Run Tests, it came back green and good, I then clicked save settings and the GD error went away.

I also have the same issue and i am unable to resolved, i have also confirmed the GD library is installed and also cleared all caches.

When i ran the tets in foo gallery i got:

Thumbnail generation test failed!object(WP_Error)#3919 (2) { [“errors”]=> array(1) { [“invalid_image”]=> array(1) { [0]=> string(21) “File is not an image.” } } [“error_data”]=> array(1) { [“invalid_image”]=> string(82) “http://customconcept.ca/wp-content/uploads/2018/06/CUSTOMCONCEPT_LOGO_FULL-web.png” } } array(2) { [“ext”]=> string(3) “png” [“type”]=> string(9) “image/png” }

Please help

I’m having a similar problem; I phoned WP Engine support and they confirmed that the GD Library is, indeed, installed (GD library Version 2.2.5) … Interestingly, the Thumbnail Generation Test fails on LIVE, but passes on the STAGING version of the site, running the same version of FooGallery. Could the CDN (CloudFlare) have anything to do with this? I can’t think of much else that is different. I tried clearing both the HTML and CSS caches under the FooGallery Settings > General tab, but neither helped.
LIVE:
Thumbnail generation test failed!object(WP_Error)#2660 (2) { [“errors”]=> array(1) { [“file-not-found”]=> array(1) { [0]=> string(0) “” } } [“error_data”]=> array(0) { } } array(2) { [“ext”]=> string(3) “jpg” [“type”]=> string(10) “image/jpeg” }
Test to see if FooGallery can generate the thumbnails it needs.
STAGING:
Thumbnail generation test ran successfully.
Test to see if FooGallery can generate the thumbnails it needs.

Please advise. THANKS! 🙂

Thanks for that suggestion. I just tried it … no change (still getting the same “Thumbnail Generation Alert!” error; so I cleared by (Chrome) browser cache, deleted the Autoptimize cache, and tried toggling and saving the changes for the FooGallery Settings > Advanced > Override Thumb Test checkbox again… Still seeing the error… Any further suggestions? … Thanks in advance!
