Howdy, not sure if this belongs on this board or not but here goes:
I've always managed to log in no problem to SadPanda, using the chrome extension, but i tried today (first time after installing Windows10 a couple of months ago) and pic related, both on Chrome and on Firefox. Anyone had the same problem/can shed some light on the situation?
Try this:
>uninstall plugin
>login to forums at ehentai
>go to exhentai
Uninstall the extension, it interferes with the way your actual supposed to do it and adds bloat
Delete cookies for everything related to ehentai, ehentai, whatever
Go to e-hentai and login
Now go to exhentai
