Image Optimization Stuck
-
Just installed your plugin and was giving it a go, it got to 30% and has been stuck since. I refreshed the page and restarted it, but that didn’t resolve anything. I enabled the error log and haven’t seen anything appear there yet either. Please advise.

My goof, there has been an error report, it seems to get stuck here.

Hi there,
Thank you for providing those logs, as they are very helpful.
It looks like the process is stalling during the WebP conversion phase. Specifically, the optimizer is identifying that a WebP version of your images already exists and is skipping them, but it seems to be getting stuck in a loop rather than moving on to the next item in the queue.
To get things moving again, I recommend trying the following steps:
- Disable WebP Temporarily: To confirm if this is the culprit, try disabling the ‘Convert to WebP’ feature in the settings and restart the bulk optimization. If it completes the 30% hurdle, we know the issue is strictly isolated to the WebP generation logic.
- Check for Conflicts: Are you using a caching plugin (like SG Optimizer) that also handles WebP? Having two tools trying to manage these files simultaneously could cause this behavior.
Let us know.
Thank you!
Hello. I have the same problem. I have deactivated webp conversion. And the conversion is stuck. No other image optimization plugins activated.
Hi,
I’m sorry to hear that. Can you please share screenshots of your current setup so we try to replicate that?
Also, can you please share if you have any errors in your debug.log file? https://breakdance.com/wordpress-error-logs/
Thank you!
