Wordpress LScache Plugin: Image optimization stopped
Last Updated on: Wed, 15 Apr 2026 00:00:02 Image optimization recently just stopped working. Its stuck at: Images requested: 308 groups (1058 images) This number hasnt changed for days. I tried cleaning up unfinished data and restarting, but the same thing happens again. My report number: NBEROTKY What should I do? The page I need help with: https://www.karolinnafoto.lt/ Theres a notify_err from our img optm server, did you install any firewall or set up object cache recently? If yes, please follow this article to add IP whitelist or this post to fix the bug, after that, try to Clean Up Unfinished Data > Reset IAPI Key > Send Optimization Data. Usually, notification error will pause the image optm process for a while, you can try it again after 1-2 days. Thanks for a prompt reply. I didnt install any firewalls, nor I enabled object cache. Nevertheless, Ive whitelisted all IPs. Then I received hash doesnt match error for one time. I tried to reset IAPI key again, but then I get this error: Failed to post via WordPress: Requested number of images exceeds allowed credit: 3790 I also used your tips to fix the bug by commenting out rows 453 ? 455, but the error remains. I find your site sometime get Error 522 Ray ID: 55619a95f96bcbf8 ? 2020-01-16 16:53:39 UTC Connection timed out This may be a reason why theres a notify_err. Could you please check on it? Also, have you put the IPs on Cloudflare whitelist? Sorry, I didnt know I had to whitelist in Cloudflare. Now they are whitelisted in my hosting provider and in Cloudflare. Please check, is it better now? Please try to run the optimization again, if it is still not working, please join our Slack channel and find me(Stanley Cheung at Litespeed). Thanks, everything seems to be fixed right now.
