Hi @forprofile, could you please provide the Report Number and let us know the broken images are on which page?
Hi!
I tried to get the Report Number, but it turns out an error. 🙁

Please update your plugin to latest version. Thanks.
Hi!
Thank you for your reply! I updated the plugin to the latest version.
Report number: EVBFDRCK
We found some of the thumbnails didn’t generate correctly, for example:
/wp-content/uploads/2019/04/red-velvet-the-red-summer-review-300x168.jpg
/wp-content/uploads/2019/04/red-velvet-the-red-summer-review-285x160.jpg
/wp-content/uploads/2019/04/red-velvet-the-red-summer-review-900x506.jpg
so when you using a different browser it might show the broken one which makes the displaying thumbnails problem.
May I know have you installed any plugin for the thumbnail generation?
Thanks a lot for the reply!
We had installed Smush for image optimization and once we re-generated the thumbnails while using it.
We didn’t notice anything weird after that though.
But that plugin is Deactivated from a long time.
Could it still cause new thumbnails problem even if it is deactivated?
Is it this problem occurred after plugin deactivated? And I found the post’s thumbnail working normally now.
Yes, that plugin was deactivated since early 2018. Back then we were on Apache, Centos, with cache by Wp Total Cache.
The thumbnails were shown normally until February 2019, when we moved to Litespeed with Litespeed cache.
But what is strange is that the thumbnails are shown differently from browser to browser.
While on a browser a thumbnail is shown as ‘broken” on a different browser the same thumbnail is shown as working fine.
The problem is still there unfortunately. 🙁

Also, we noticed that if the server is down for a second, that error will be shown for a few hours. Visitors will see the page they were on while the error occurred, as broken for many hours, while they can browse the rest of the site normally.
Could you check your PHP error log to see if there any error related to those image files or timeout issue? If you are not sure about it, you can send us the error log for checking. Thanks.
And for We noticed that if the server is down for a second, that error will be shown for a few hours which error did you see? Could you describe more about it?
Thank you for your answer!
We also noticed that when you click on a thumbnail image that isn’t displayed correctly and try to open that image in a new tab, the image URL seems correct but it directs to a random page URL instead not to an image url.

This happens randomly on a browser while it works correctly on a different browser.
It acts really strange. 🙁
Here is the error log: https://mega.nz/#!xUZTyQTa!nr0824fDBoNoN7mpZK0oAUe8hVWe-kUzKr7Ek_LN-GQ
The error I was talking about is the typical 502 error that is shown when the server goes down: https://i.imgur.com/HjnoZnQ.png
If the server goes down for like 2 seconds and a user is browsing a certain page that time, that error will be automatically cached and served to the user for a few hours (usually until we manually empty the entire cache).
Hi, could you please join our Slack channel or submit a ticket here for helping us to reproduce the bug, thanks!
Sorry for the late reply, we reinstalled Ubuntu and Litespeed, deactivated the plugins that weren’t needed and re-uploaded the thumbnails with problems. For now everything seems back to normal! 😀
Thanks a lot for your guidance!
