Joomla extension PWA

Hello Mr Bela,
First up, thanks for the Gzip extension. I had used it prior, and it worked. Secondly, I'm not a developer.
I've tried Gzip now on another https site, twice, last week and today, and both times, I was thrown and locked out of my Admin back-end. The only changes I've made since, was to install security (SecurityCheck) and also backup (EJB).
Could this be the reason why Gzip is throwing me out, giving a blank page, and locking me out?
Or are there other possible reason?
Thanks
Jacquelene

Exclude path images (duplicate images)

Hi.
This is not Issues maybe a little.
If any gallery create optimize image in src in own breakpoints.
Duplicating images. Even if they are not webp This profit will be minimal at the expense of the space occupied.

Maybe gzip be smart and discover image src set or option for exclude patch cache images for gallery support src set.

DJ mediatools, econa, droppic, JUltraNewsPRO using src set.
