MySQL error "Expression #1 of ORDER BY clause is not in GROUP BY clause"

I am trying to fetch total number of records from a table and using the following MySQL query:

SELECT COUNT(*) AS cnt FROM `info` WHERE 1 GROUP BY FROM_UNIXTIME(signup_date, '%Y-%m-%d') ORDER BY signup_date DESC

but it is resulting in the following error:

SQL Error(1055): Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column 'rentown.info.signup_date' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by.[SELECT COUNT() AS cnt FROM info WHERE 1 GROUP BY FROM_UNIXTIME(signup_date, '%Y-%m-%d') ORDER BY signup_date DESC]

and here is my table format:

+ Options
    id  email   signup_date     ip  city_name   firstname   address     state   lastname    city    zipcode     phonenumber     current_url     creditscore

For a total number of records, this should be enough:

SELECT COUNT (*) AS cnt
FROM 'info'
ORDER BY signup_date DESC

The error message is pretty self-explanatory. You can only order by columns appearing in the GROUP BY clause or aggregates. For a quick fix, just order by the same term you used when grouping.

SELECT COUNT(*) AS cnt
FROM `info`
GROUP BY FROM_UNIXTIME(signup_date, '%Y-%m-%d')
ORDER BY FROM_UNIXTIME(signup_date, '%Y-%m-%d') DESC
