Thumbnail Generation Alert!

i have the same issue (host gator vps)

@toad75 sometimes this happens when test thumb generation fails.

Goto FooGallery -> Settings -> Advanced Tab

Check the “Override Thumb Test” setting and click save

Give that a try

Hi,
I have this as well – Thumbnail Generation Alert!
The only thing is, that the thumbnails are being generated.
So is it safe to just ignore this alert?

I’ve tried some of the suggestions above but didn’t notice anything different.

Thanks

@cluain404 if the thumbs are being generated correctly, then you can ignore the alert.

Thanks very much.

I am having this same issue at ExtinctDisney.com (hosted by BlueHost). The full error is:
Thumbnail Generation Alert!
There is a problem generating thumbnails for your gallery. Please check that your hosting provider has the GD Image Library extension installed and enabled.
If thumbnails cannot be generated, then full-sized, uncropped images will be used instead. This will result in slow page load times, and thumbnails that do not look correct.

I have tried checking the “override thumbs test” with no change. I’ve cleared FooGallery cache with no change.

I’m getting this error also:

Thumbnail generation test failed!object(WP_Error)#5242 (2) { [“errors”]=> array(1) { [“invalid_image”]=> array(1) { [0]=> string(21) “File is not an image.” } } [“error_data”]=> array(1) { [“invalid_image”]=> string(69) “https://southerngeorgianbay.ca/wp-content/uploads/logo_midland-002.png” } } array(2) { [“ext”]=> string(3) “png” [“type”]=> string(9) “image/png” }

It’s because I updated the website to use https instead of http. The images aren’t found because they have https://. I used the Better Search Replace plugin to properly find all https://southerngeorgianbay.ca and replace with https://southerngeorgianbay.ca, the rest of the site is working fine and is secure, but wherever the above data is store is not getting updated…

Any suggestions?

Figured it out… the Better Search Replace plugin doesn’t replace text in guids by default… Once I forced that to happened, it worked.

I have the same problem

This worked for me

Yes, I just checked. Hosting confirms Installed and enabled.
Foogallery Systems Settings indicates it is loaded.

Nothing resolved: Fo Gallery still shows “Thumbnail generation error”. Ovverriding test and clearing cache does not help.

Here ist the result of the test: Thumbnail generation test failed!object(WP_Error)#8263 (2) { [“errors”]=> array(1) { [“invalid_image”]=> array(1) { [0]=> string(20) “Datei ist kein Bild.” } } [“error_data”]=> array(1) { [“invalid_image”]=> string(40) “https://s3.amazonaws.com/foocdn/test.jpg” } } array(2) { [“ext”]=> string(3) “jpg” [“type”]=> string(10) “image/jpeg” }

Besides, my provider does not habe the Module “imagick” – but I do not think this is the questeion.
My site https://aschihaas.ch is running without problems, so it seems we have no possibility to get rid of the message. Should we simply ignore it?

Tanks for for any suggestion, Aschi

I have made some improvements to the thumbnail generation test code, which I think will help. These updates will be released in v1.9.27 of FooGallery
