I didn't see a post on how to fix this and it just happened recently.
Check the error log for your web server.
For example, on Ubuntu, check /var/log/apache2/error.log and you
may see the reason for the problem. For example:
[error] [client 127.0.0.1] PHP Warning: Unknown: Input variables
exceeded 1000. To increase the limit change max_input_vars in php.ini. in
Unknown on line 0, referer: http://localhost/mythweb/settings/tv/channels
If you see the above error, then add the following line to
max_input_vars = 100000
(I don't know exactly how big the number has to be but the above worked).
Then restart apache:
service apache2 restart
I'm guessing the reason this started happening is related to a newer
version of php that introduces a new variable, "max_input_vars" that
is used to prevent Denial of Service attacks. See
for more details on that.
