Update: When I try to debug it, the problem really seems to come from the following line

“$mask = -1 << (32 – $bits);”

In the

“cidr_match($ip, $range)”

function.

I removed all IPv6 adresses for now because some of my users reported me that the website is crashing and sent me the following screenshot:

I now tried it with the newest version of the plugin but it still does not work.

This is the IP range with the exact notation I wanted to block:

“2a02:3037:60e:8982:51c0:8497:a9e:8222/48”

And this is the entry from the debug.log:

{"time":"2023-08-05 18:27:12","client_ip":"2a02:3037:60e:8982:51c0:8497:a9e:8222","country":"DE","is_proxy":"NO","proxy_type":"-","lookup_by":"??","cache":true,"uri":"https:\/\/www.my-website.de\/","message":"Access is allowed.","action":"ABORTED"}

Furthermore the error.log of my server is full of these entries:

(I needed to replace some numbers in the last log for data protection)

This time it seemed to work when I wanted to block a single IPv6 adress but the range is not working.

I found a different issue. No matter how big I set the maximum image width and height, the downscaled version never gets bigger than 2560px. If I set it to 1000x1000px it works but 4000x4000px for example do not work.

Interestingly I’ve tried it on my Windows PC in Chrome and on my Windows Tablet in Chrome now, and on the PC it always works but not on the tablet with very big images.

I am going to try a few things and report back if I find something new.

Don’t you resize the image on the server? So it has to get uploaded before it get’s resized?

If not, maybe it is a problem with my browser.
