I have a problem with the issue tracker of Frontier. It's been three days i'm trying to update this issue. but every time I try to upload it gives me an error.
I tried to delete caches but didn't work. I don't know what else to do
You're essentially reporting a case of a wider issue that conflicts (elections or wars, in both new and previously-settled systems) don't always progress each day as they should.
There's a report already at https://issues.frontierstore.net/issue-detail/73217 of the general problem which you can add your own confirmation to, which will be a lot more useful than a separate report of your specific system
As for what the issue tracker is specifically doing wrong for you, it's a known issue with it randomly rejecting certain web browsers / configurations. I've got some screenshots at https://forums.frontier.co.uk/threads/cobra-mk-v-left-keyboard-console.631606/#post-10507974 if you want to see the details and try a different browser; in this specific case, as it only affects reporting new bugs, it shouldn't stop you adding your own info to bug 73217.
It did stop me to add my own info to bug 73217
I'll try a different browser, I wished to know what I should change in order to prevent this with chrome
