Problem with the correct operation of pihole 5.0

[locar]

Hello, since yesterday I have a problem with the correct operation of pihole.

It seems to work and filters traffic (at least I see it on the main panel), but I can't log in to the administrative panel in the web interface at all. In the console, no command works, and after writing any I get something like this

pi@Pi-Zero:~ $ pihole -r
/usr/local/bin/pihole: linia 4: syntax error with unexpected tag `c'
/usr/local/bin/pihole: linia 4: `3 (c) 2017 Pi-hole, LLC (https://pi-hkle.net)'

What could be wrong, this problem can be somehow solved ??

Something is wrong with you pihole.sh in/usr/local/bin/pihole
Line 4 should look like this

# (c) 2017 Pi-hole, LLC (https://pi-hole.net)

What did you do yesterday? Which version of Pihole are you running? On which system?

Actually, I did nothing and everything was fine. At night I had a power outage and although the pihole is connected to the UPS, the main router has reset. This morning I look and the status tab is "Unknown" instead of "Activ". So he reset the RPI, but it did nothing.

I use PiHole v 5.0 wagered on Raspberry Pi Zero.

Dirty fix without knowing what really happend:

Replace the content of your `/user/local/bin/pihole with this
https://raw.githubusercontent.com/pi-hole/pi-hole/master/pihole

Swapping files helped but partly (I don't know why but some of the characters in this file have been changed.

Unstable, despite entering the correct password, I cannot log in to the web palette.

If I use pihole -r will all statistics be deleted or not ??

Normally the should stay intact. You could backup pihole-FTL.db manually before.

after entering the address "http://192.168.1.8/admin/settings.php" from the palace, it was possible to enter the administration panel but an error pops up

There was a problem applying your settings.
Debugging information:
PHP error (2): session_start(): Failed to read session data: files (path: /var/lib/php/sessions) in /var/www/html/admin/scripts/pi-hole/php/password.php:12

How do I set or reset the Web interface Password?

The Web interface password needs to be reset via the command line on your Pi-hole. This can be done locally or over SSH. You will use the pihole command to do this: pihole -a -p You will be prompted for the new password. If you enter an empty password, the password requirement will be removed from the web interface.

I've already done it but it doesn't help

Try pihole - r

Ehs, I think some fatal failure at pihole -r I get something like this

I had a power outage a

Think your SD card might have become corrupt after this.

Best bet might be to reflash it at this point...
