Yes, I'm familiar with that bug. I've updated the GDPR pkg recently to fix it. It's a BC break introduced in 8.4.4+, I think. I'll take a look for Image Optimizer.

I submitted version 3.2.7 which should have the issue resolved. Thanks for reporting!

Cool...

Just downloaded the lates version and this issue still seems to be present on 8.5.1:

Call to a member function useLogger() on null

@katalysis that's another bug. Please check the QueueMessages database table and remove all records that derive from Image Optimizer. This is safe to do. Then start the job again (preferably via CLI).

The reason for this bug is:
- In earlier versions a different reference to a file was used (e.g. fID instead of fileId).
- Apparently not all images were optimized before you upgraded the add-on.

In the meantime I'll see if I can release an update to get around this problem as well.

QueueMessages table is actually empty.

This error is only triggered when processing the queue, so... that's odd.

I've uploaded version 3.2.9. I hope that fixes the issue for you!
