Hi Matomo community,
I’m running a self-hosted Matomo instance, and I’ve been using it for about a year now. I’m currently on the latest version, Matomo 5.3.1.
Everything has been working great, and all statistics are collected normally. However, I’m encountering a specific issue with the date comparison feature, specifically when using “User Defined” comparison with calendar date selection.
Problem Description:
The issue occurs when I try to compare data for a specific date range using the “User Defined” option and selecting dates directly from the calendar.
Scenario: Let’s say I want to compare data for March 25th, 2025 with March 7th, 2025.
Steps to reproduce:
- Go to any report in Matomo.
- Select the specific date at the top (e.g., currently showing “2025-03-21”).
- In the date picker popup, choose “Compare to” and then select "User Defined.
- Select specific date (compare date)
- Click the “Apply” button.
Expected Result: The report should load, comparing the data for the selected date (March 25th) with the user-defined date (March 7th).
Actual Result: I get an error message and the report fails to load.
- Browser Console Error (from the previous response):
POST https://...../index.php?date=2025-03-07&forceView=1&viewDataTable=sparklines&module=VisitsSummary&action=get&disableLink=0&widget=1&comparePeriods%5B%5D=range&compareDates%5B%5D=%2C&idSite=7&period=day 500 (Internal Server Error)
Notice the compareDates%5B%5D=%2C part in the POST request. It seems the compareDates parameter is being sent with just a comma, indicating that the date is not being properly passed when selected from the calendar.*
- On the screen error.
Valid date format: YYYY-MM-DD, or 'today' or 'yesterday' or any keyword supported by the strtotime function (see http://php.net/strtotime for details): false
I’ve already checked my PHP code, but I haven’t been able to find any obvious issues related to date handling.
Can someone tell me how do i fix this?
Thank you.
