Hi again - just took a look at my server error logs and these two entries might help you read the problem:
(22)Invalid argument: AH01075: Error dispatching request to :, referer: Sign in - Matomo
AH01068: Got bogus version 100, referer: Sign in - Matomo
Also … I did a Matomo “system check” and discovered this database issue - not sure if it’s relevant but I will need to repair it in due course when I work out how to do it:
LOAD DATA INFILE
Using LOAD DATA INFILE will greatly speed Matomo’s archiving process up. To make it available to Matomo, try updating your PHP & MySQL software and make sure your database user has the FILE privilege.
If your Matomo server tracks high traffic websites (eg. > 100,000 pages per month), we recommend to try fix this problem.
Error: LOAD DATA INFILE failed… Error was:
Try #1: LOAD DATA INFILE : SQLSTATE: Invalid authorization specification: 1045 Access denied for user ‘wiz2_analytics’@‘localhost’ (using password: YES)
